Journal ArticleDOI
Broadband microwave absorption and shielding properties of a poly(aniline)
TL;DR: In this article, the authors report comprehensive, cumulative broadband measurements and computations of all microwave parameters of a conducting polymers (CPs) relevant for practical application, viz., conductivity, absorption, complex permittivity, shielding and reflection.
Journal ArticleDOI
Phase-Based Methods for Heart Rate Detection Using UWB Impulse Doppler Radar
TL;DR: To further enhance the accuracy of the HR estimation, a recently developed state-space method has been successfully combined with CSD and AD techniques and over 10 dB improvements in SNR is demonstrated.
Journal ArticleDOI
Carbon-Nanotube Loaded Antenna-Based Ammonia Gas Sensor
Hoseon Lee,George Shaker,Krishna Naishadham,Xiaojuan Song,M.D. Mckinley,B. Wagner,Manos M. Tentzeris +6 more
TL;DR: In this article, a planar sensor fabricated on paper substrate to detect small concentrations of ammonia gas, using the shift in resonance frequency of a patch antenna as the discriminator, is presented.
Journal ArticleDOI
Measurement of the microwave conductivity of a polymeric material with potential applications in absorbers and shielding
Krishna Naishadham,P.K. Kadaba +1 more
TL;DR: In this paper, the microwave conductivity of a new material, the polymer poly-p-phenylene-benzobis-thiazole (PBT) made conductive by ion-implantation doping with iodine, is measured at 9.89 GHz as a function of temperature using the cavity perturbation technique applicable to thin films of arbitrary shape.
Journal ArticleDOI
RF equivalent circuit modeling of ferrite-core inductors and characterization of core materials
TL;DR: In this article, the authors proposed a technique for extracting the equivalent circuit parameters of the inductor and determining the frequency-dependent effective rod permeability as well as the intrinsic permeability of the ferrite-core material.
