A review and analysis of microwave absorption in polymer composites filled with carbonaceous particles

Abstract: Carbon (C) is a crucial material for many branches of modern technology. A growing number of demanding applications in electronics and telecommunications rely on the unique properties of C allotropes. The need for microwave absorbers and radar-absorbing materials is ever growing in military applications (reduction of radar signature of aircraft, ships, tanks, and targets) as well as in civilian applications (reduction of electromagnetic interference among components and circuits, reduction of the back-radiation of microstrip radiators). Whatever the application for which the absorber is intended, weight reduction and optimization of the operating bandwidth are two important issues. A composite absorber that uses carbonaceous particles in combination with a polymer matrix offers a large flexibility for design and properties control, as the composite can be tuned and optimized via changes in both the carbonaceous inclusions (C black, C nanotube, C fiber, graphene) and the embedding matrix (rubber, thermoplastic). This paper offers a perspective on the experimental efforts toward the development of microwave absorbers composed of carbonaceous inclusions in a polymer matrix. The absorption properties of such composites can be tailored through changes in geometry, composition, morphology, and volume fraction of the filler particles. Polymercomposites filled with carbonaceous particles provide a versatile system to probe physical properties at the nanoscale of fundamental interest and of relevance to a wide range of potential applications that span radar absorption, electromagnetic protection from natural phenomena (lightning), shielding for particle accelerators in nuclear physics, nuclear electromagnetic pulse protection, electromagnetic compatibility for electronic devices, high-intensity radiated field protection, anechoic chambers, and human exposure mitigation. Carbonaceous particles are also relevant to future applications that require environmentally benign and mechanically flexible materials.

Analysis of EMI Terminal Modeling of Switched Power Converters

Abstract: A generalized terminal modeling technique was proposed earlier to predict conducted electromagnetic interference from a dc-dc boost converter. The predictions of these conducted emissions showed that there was a good agreement up to 50 MHz. This paper extends the generalized terminal modeling approach to converters with the buck-type input. Both dc and ac applications are discussed. The technique is developed for the electromagnetic interference modeling of switched power converters in aerospace applications where the requirements on electromagnetic pollution are very strict. The model is shown to successfully predict conducted emissions for a buck converter and a three-phase voltage source inverter up to 100 MHz with an error of 6 dB or less at most frequencies.

Finite Element Computation of Magnetic Vibration Sources in 100 kW Two Fractional-Slot Interior Permanent Magnet Machines for Ship

Abstract: The design of an interior permanent magnet (IPM) machine, in particular, its pole and slot combination, determines the nature of its magnetic forces, which influences not only the torque but also acoustic noise and vibration characteristics. Vibrations can shorten bearing life and are an especially important parameter in marine applications, which have strict regulations such as on electromagnetic compatibility. In this study, two-dimensional(2D) finite element analysis (FEA) was used to model magnetic vibration sources in two 100-kW marine fractional-slot IPM machines with different pole and slot combinations (8 pole-12 slot and 10 pole-12 slot). The magnetic forces were calculated according to rotor position, current phase angle, and load. The results are validated by experiments.

Electromagnetic Compatibility-Oriented Study on Through Silicon Single-Walled Carbon Nanotube Bundle Via (TS-SWCNTBV) Arrays

Abstract: Electromagnetic compatibility-oriented study is performed for accurately characterizing through silicon single-walled carbon nanotube bundle via (TS-SWCNTBV) array in this paper. Based on the modified equivalent lumped-element circuit model of a pair of TS-SWCNTBVs, its forward transmission coefficient, in comparison with copper- and tungsten-based TSVs, is investigated for different metallic fractions of the SWCNTs, with quantum effects treated appropriately. The 3-D transmission-line method (TLM) is further employed for studying mutual couplings in three, four, and nine TS-SWCNTBV arrays, respectively, where the effects of their geometrical and physical parameters on the effective capacitance and conductance are examined in detail. Also, transient coupling noises in different arrays excited by a clock signal, respectively, are predicted and compared, which are useful for the design of high density TS-SWCNTBV arrays with better signal transmission performance.

Compact Configuration for Common Mode Filter Design based on Planar Electromagnetic Bandgap Structures

Abstract: A planar electromagnetic bandgap configuration of a compact common mode filter that is laid out on printed circuit board is studied. This filter is used to mitigate the common mode noise traveling on high-speed differential signal traces. These differential signal lines may be connected to I/O connectors and cables and small amounts of common mode noise can result in significant electromagnetic emissions. The filter is obtained by a very simple planar geometry based on the electromagnetic bandgap structures. A cavity made by a rectangular/square patch (together with a solid plane underneath) has a well known and predictable resonant behavior; the coupling between the differential pair routed on top of the patterned plane and the patch cavity, occurring when the traces cross the gap between adjacent patches, is used to reduce the energy associated with the propagation of the common mode noise. The properties of this filter are studied taking into account the layout of a real differential microstrip and the number of gap crossings. A compact configuration is proposed. Time domain simulations validate the suggested layout approach.

Experimental Validations of a Simple PCB Interconnect Model for High-Rate Signal Integrity

Abstract: This paper is devoted to investigating experimental validations of a simple modeling method of PCB interconnects for high-speed signal integrity and electromagnetic compatibility applications. Based on the theoretical approach using the extraction method of the interconnect per-unit-length RLCG parameters, the reduced models of the corresponding transfer function, -parameters, and access and transfer impedances are also established. The methodology describing the different steps of the technique proposed for practical use cases in ultra wideband is established. To verify the effectiveness of the concept under consideration, time-domain validations from the frequency-measured data are realized by using printed circuit board microstrip interconnect lines with micrometers width and millimeters long. Therefore, the model was first validated experimentally, and with electromagnetic simulations, in frequency domain via comparison of -parameters and -matrix from dc to some gigahertz. It was found that relative errors lower than 1 dB were evaluated between the insertion loss of the models, simulations, and measurements. Then, by injecting noisy digital- and mixed-signals with 1 Gigasymbol/s, relative errors of lower than 1% were evaluated by considering the time-domain responses. Compared to the existing interconnect modeling tools, the developed one presents a high accuracy, simplicity, and very less computation time.

Study of the Susceptibility of the GSM-R Communications Face to the Electromagnetic Interferences of the Rail Environment

Abstract: The Global System for Mobile Communications-Railway (GSM-R) system is currently deployed in Europe in order to ensure the interoperability of the high-speed trains. Knowing that data related to control and command will be transmitted to trains through this communication system, the immunity of the GSM-R system against electromagnetic disturbances on board trains has to be certified. After a background about the GSM-R communication system, we will present in detail the typical disturbances that can affect this system in the railway environment. Significant differences between these disturbances and the test signals defined in the current European electromagnetic compatibility standards will be highlighted. The criteria that can be employed to evaluate the immunity of the GSM-R transmissions will then be discussed. Finally, new test signals and immunity test bench will be presented in order to expose the GSM-R transmissions to noise scenarios representative of the railway environment. Different immunity results will be presented and analyzed.

On-Chip Noise Sensor for Integrated Circuit Susceptibility Investigations

Abstract: With the growing concerns about electromagnetic compatibility of integrated circuits, the need for accurate prediction tools and models to reduce risks of noncompliance becomes critical for circuit designers. However, an on-chip characterization of noise is still necessary for model validation and design optimization. Although different on-chip measurement solutions have been proposed for emission issue characterization, no on-chip measurement methods have been proposed to address the susceptibility issues. This paper presents an on-chip noise sensor dedicated to the study of circuit susceptibility to electromagnetic interferences. A demonstration of the sensor measurement performances and benefits is proposed through a study of the susceptibility of a digital core to conducted interferences. Sensor measurements ensure a better characterization of actual coupling of interferences within the circuit and a diagnosis of failure origins.

Modelling dielectric-constant values of concrete: an aid to shielding effectiveness prediction and ground-penetrating radar wave technique interpretation

Abstract: A number of efficient and diverse mathematical methods have been used to model electromagnetic wave propagation. Each of these methods possesses a set of key elements which eases its understanding. However, the modelling of the propagation in concrete becomes impossible without modelling its electrical properties. In addition to experimental measurements; material theoretical and empirical models can be useful to investigate the behaviour of concrete's electrical properties with respect to frequency, moisture content (MC) or other factors. These models can be used in different fields of civil engineering such as (1) electromagnetic compatibility which predicts the shielding effectiveness (SE) of a concrete structure against external electromagnetic waves and (2) in non-destructive testing to predict the radar wave reflected on a concrete slab. This paper presents a comparison between the Jonscher model and the Debye models which is suitable to represent the dielectric properties of concrete, although dielectric and conduction losses are taken into consideration in these models. The Jonscher model gives values of permittivity, SE and radar wave reflected in a very good agreement with those given by experimental measurements and this for different MCs. Compared with other models, the Jonscher model is very effective and is the most appropriate to represent the electric properties of concrete.

On-chip protection for automotive integrated circuits robustness

Abstract: On-chip protection architecture for automotive ICs (integrated circuits) system-level robustness is introduced. It comprises three-level protection for interface pins with high bidirectional voltage swing. A first protection stage is optimized to sustain the largest portion of the ESD (electrostatic discharge) and EMI (electromagnetic interference)-induced stress. A second-level protection stage is customized to sustain the relatively lower IC-level ESD stress, and the third level protection stage absorbs the initial transient voltage impulse.

Analytical Expressions for Electromagnetic Fields Associated with the Inclined Lightning Channels in the Time Domain

Abstract: This article describes general analytical equations that are developed for the calculation of electromagnetic fields due to an inclined channel directly in the time domain. The input parameters of the model, angle of inclination of the lightning channel and the angle at the observation point can be varied through all possible values to produce the relevant electromagnetic fields. The proposed model is validated with eight electromagnetic waveforms measured at close range of the lightning channel. The results of the model show good agreement with the measured data. Furthermore, the proposed equations are compatible with different channel base current functions. The equations could easily be applied in the coupling models that calculate induced voltages in conductors in the presence of lightning-generated electromagnetic fields.

Meshing power quality and electromagnetic compatibility for tomorrow's smart grid

Abstract: With the onset of the smart grid, electric utilities and their customers are engaged in millions of dollars of research on smart grid technologies. There are hundreds of smart grid topics being studied by dozens of organizations including the Electric Power Research Institute (EPRI). One of the topics in the electric utility industry that has been (and still is) of significant importance to utilities is power quality (PQ). The reliable and compatible performance of end-use equipment requires, in part, quality power at the power frequencies of 50 or 60 hertz up to about 3 kHz. Compatibility with the surrounding electromagnetic environment above 3 kHz (i.e., up to 10 GHz and beyond) is also a must in today's changing environment. Electromagnetic compatibility (EMC) is paramount if electronic loads - used to operate the grid and in customer facilities - are to interoperate with the power system and other loads on the grid. This article will help the reader to understand why EMC, bundled with PQ, must be co-addressed as the smart grid takes shape in the next few decades.

A domain decomposition method for analysis of three-dimensional large-scale electromagnetic compatibility problems

Abstract: This dissertation work investigates the numerical method for solving Electromagnetic Compatibility (EMC) problems involving electrically large and complex platform. Numerical simulation of the antenna couplings on the aircraft is of great interest in EMC community. Conventional Computational Electromagnetics (CEM) solvers suffer inefficiency and inflexibility in modelling this kind of problems. One of the challenges comes from the multi-scale physics in the geometry containing both electrically large platform and antennas with electrically small structures. Also, using conventional CEM solvers, the user may have the dilemma of choosing between the Partial Differential Equation (PDE) based methods , like Finite Element Method (FEM), which are convenient and accurate in modelling complex materials but requires volume mesh, and Integral Equation (IE) based methods, which only require surface discretization but are not convenient in modelling antennas with complex materials. In this dissertation, a Multi-Solver Domain Decomposition Method (MSDDM) has been proposed to model the problems with electrically large and complex structures. Using MSDDM, the problem of antenna coupling can be decomposed into antenna sub-domains and platform sub-domains, for which different CEM solvers can be applied. This gives an efficient way to precondition the global system. It hybridizes the strength of PDE based methods and IE methods. Also, the CEM solvers in MSDDM

Multi-peaked functions for representation of lightning channel-base currents

Abstract: A new function is presented in this paper for representation of multi-peaked currents of lightning strokes. Experimentally measured lightning channel-base currents often have a few emphasized peaks. If such currents are approximated with a suitable analytical function, having analytical integral and derivative, lightning electromagnetic field is calculated based on some engineering, electromagnetic or other model of lightning strokes. For the function presented in this paper and two engineering models with new attenuation factors, calculated field results at different distances from the channel base are in better agreement with measurements. Analytically obtained Fourier transform of this function is useful for calculations of lightning electromagnetic field at a lossy ground.

Electromagnetic Measurements in the Near Field

Abstract: This book is devoted to the specific problems of electromagnetic field (EMF) measurements in the near field and to the analysis of the main factors which impede accuracy in these measurements. It focuses on careful and accurate design of systems to measure in the near field, based on a thorough understanding of the fundamental engineering principles and on an analysis of the likely system errors. Beginning with a short introduction to electromagnetic fields with an emphasis on the near field, it then presents methods of EMF measurements in near field conditions. It details the factors limiting measurement accuracy including internal ones (thermal stability, frequency response, dynamic characteristics, susceptibility) and external ones (field integration, mutual couplings between a probe and primary and secondary EMF sources, directional pattern deformations). It continues with a discussion on how to gauge the parameters declared by an EMF meter manufacturer and simple methods for testing these parameters. It also details how designers of measuring equipment can reconsider the near field when designing and testing, as well as how users can exploit the knowledge within the book to ensure their tests and results contain the most accurate measurements possible. The SciTech Publishing Series on Electromagnetic Compatibility provides a continuously growing body of knowledge in the latest development and best practices in electromagnetic compatibility engineering. This series provides specialist and non-specialist professionals and students practical knowledge that is thoroughly grounded in relevant theory.

Transient Excitation of Rectangular Resonators Through Electrically Small Circular Holes

Abstract: In this paper, analytical solutions of response functions for rectangular resonators are investigated in time domain. Emphasis is placed on the study of electromagnetic field coupling to a 3-D cavity through a small circular aperture. The time-dependent parts of the resulting modal Green's functions exhibit typical behavior that is inherent in all resonating/oscillating linear physical systems: namely, they fulfill oscillating ordinary differential equations at any point of the considered resonator. Their solutions contain transient and steady-state parts. The transient parts of the response functions will become important for electromagnetic compatibility tests in particular of modern digital high-speed electronics.

Interference mitigation in WSN by means of directional antennas and duty cycle control

Abstract: Network spanning algorithms, such as ZigBee-native and Stojmenovic, constitute a crucial element in the wireless sensor network design, by determining its potential for reliability and fault-tolerance. The interconnections between nodes have a great impact on the radio interference level present in such a network and may create a serious electromagnetic compatibility issue in some cases. It can be proved that the total interference incurred by a statistical node can be diminished in two ways: either by using directional antennas or by setting an upper limit on the duty cycle of each network node.

Development of a grid simulator

Abstract: A grid simulator is required to have control over the key grid characteristics that may expose system compatibility problems related to the integration of distributed generation (DG) to the ac grid. This paper presents the development of a grid simulator that provides controllability of the impedance, voltage, harmonics and frequency at the ac interconnection of several DG units. In the implementation of the grid simulator using a back-to-back VSC topology, resolving problems of electromagnetic compatibility (EMC) are essential to yield a reliable and safe grid simulator operation. Various experimental measurements are presented to verify the grid simulator control system and its electromagnetic interference (EMI) filter design.

Effect of the MOSFET choice on conducted EMI in power converter circuits

Abstract: The phase of virtual prototyping, which is usually based on a whole of numerical simulations of the system, requires today to have thin suitable models. These models must take in account the real behavior of the systems under various physical constraints (thermal, electromagnetic...). Particularly, in this work, we are interested to the study of the effect of the Mosfet transistor choice on the conducted electromagnetic interferences emitted by static converters circuits. The objective of this work is to propose a new design methodology which will permit to assist the power electronics circuit designer in the choice of the active components with the purpose of reducing the electromagnetic disturbances.

Emulating an Anechoic Environment in a Wave-Diffusive Medium Through an Extended Time-Reversal Approach

Abstract: A generalized time-reversal (TR) technique for the generation of coherent wavefronts within complex media is presented in this paper. Although completely general, this method is primarily considered for testing purposes herein, where an equipment under test is submitted to a series of impinging wavefronts with varying features. Electromagnetic compatibility, antenna testing as well as telecommunications facilities where complex-wavefront schemes (e.g., multi-path configurations) are required, could benefit from the proposed approach. The main advantages and limitations of current standard TR approaches are reviewed in this respect, exposing their inadequacy for this particular context. The proposed alternative technique, named time-reversal electromagnetic chamber (TREC) is introduced and studied by means of a formal theoretical analysis, showing how a reverberation chamber (RC) supporting a diffused-field condition can be operated as a generator of deterministic pulsed wavefronts. The TREC is demonstrated to be capable of generating arbitrary wavefronts with a remarkable accuracy, allowing to revisit the RC as a deterministic facility: the main advantages of RCs and anechoic ones are merged, leading to a new facility capable of potentially generating in real-time pulsed wavefronts while using low input energies, without requiring neither mechanical displacements nor any special features of the sources.

An EMI receiver model to evaluate electromagnetic emissions by simulation

Abstract: Electromagnetic Compatibility (EMC) standards generally limit the electromagnetic emission (EME) of products, e.g. assembled in a vehicle. The compliance to EME standards is verified by emission measurements using a defined test setup including electromagnetic interference receivers (EMI Receivers). Integrated circuits undergo extensive simulations before they are actually produced. More and more, the electromagnetic emission are also considered and simulated during the product design phase. Consequently, the behaviors of all components that are required for an EMC test have to be included in the simulation. This paper investigates the modeling of an EMI receiver and presents an implementation with short computation time. The model is verified with various test signals.

Time Reversal Efficiency Measurement in Reverberation Chamber

Abstract: The time reversal (TR) technique is applied in a reverberation chamber (RC) to perform an analysis of antenna efficiency. RC are mainly used for electromagnetic compatibility measurements. They provide through a stirring process the total radiated power from any electromagnetic source placed inside these overmoded cavities with a reasonable statistical uncertainty. Performances of TR techniques also increase with the number of modes or path densities, inherently high in RCs. In this paper, we show how a RC may be used in combination with the TR technique to measure ultra wide band (UWB) antenna efficiency with simple operation all over the frequency band. Principles of this new method called time reversal efficiency measurement (TREM) are provided together with experimental validations. Results are discussed and compared with simulations or other measurement methods.
