What are the methods to measure the intrinsic quality factor of a resonator? 


Best insight from top research papers

There are several methods to measure the intrinsic quality factor (Q-factor) of a resonator. One method involves measuring the proper Q-factor of a volumetric metal resonator and then calculating the Q-factor of the open dielectric resonator based on the resonance frequency and coupling coefficients . Another approach is to use a general Q-factor measurement system, which includes excitation of the resonator, acquisition of the resulting signal, and signal processing to determine the Q-factor. This can be done in the frequency domain, time-frequency domain, or time domain, with the time domain approach being the only way to conduct an in-situ Q-factor measurement . Additionally, a novel method involves using thermoelastic dissipation (TED) to trim the Q-factor of a 2-axis mode-matched resonator, allowing for independent modification of the Q-factors of each axis .

DO YOU HAVE INFORMATION ABOUT Characterization of Helmholtz resonator with Non-rigid bases using laser Doppler vibrometry?5 answersCharacterizing Helmholtz resonators with non-rigid bases using Laser Doppler Vibrometry (LDV) can be achieved efficiently through techniques like Continuous Scanning LDV (CSLDV). LDV is a non-invasive technology that provides accurate full-field measurements, crucial for complex mechanical structures like Helmholtz resonators. Additionally, LDV can be used to experimentally obtain deflection mode shapes, calibrate actuation gains, and determine dynamic modal stiffnesses, which are essential for analyzing resonant behavior in structures like Helmholtz resonators. Furthermore, LDV can visualize wave propagation and resonance patterns in devices like Helmholtz resonators, aiding in the detection of undesired responses and optimizing device performance. Therefore, utilizing LDV techniques can offer valuable insights into the vibrational characteristics of Helmholtz resonators with non-rigid bases.
What are the factors that affect the generation of higher harmonics in an electrostatic MEMS resonator?4 answersThe factors that affect the generation of higher harmonics in an electrostatic MEMS resonator include the non-linear oscillation of the resonator in the non-linear region. By driving the resonator with a single tone frequency in the non-linear region, multiple high order harmonic frequencies can be generated. The presence of harmonics can be confirmed electrically and optically through measurements using a Spectrum Analyzer and a Laser Doppler Vibrometer (LDV) respectively. Additionally, the use of a repulsive force electrostatic resonator can create combined responses that exhibit parametric and subharmonic resonance when driven at twice its natural frequency. Furthermore, the use of 2nd harmonic operation can enhance the quality factor (Q) and improve the resonance peak of the resonating system. Overall, the generation of higher harmonics in an electrostatic MEMS resonator is influenced by the non-linear behavior of the resonator, the driving frequency, and the resonator design and characteristics.
What are the typical semiconductor laser intrinsic parameters?5 answersSemiconductor laser intrinsic parameters include the phase-amplitude coupling factor α, optical gain, transparency wavelength, optical loss, linewidth enhancement factor, differential gain, and wavelength chirp. The small-signal modulation and noise properties of laser diodes depend on these parameters, which are specific to the semiconductor material employed. The extraction of these parameters can be achieved through techniques such as intermodulation measurement of distortion products and optimization algorithms. Additionally, the temperature dependence of the threshold current and the output power characteristics are also important parameters for semiconductor lasers. The design of semiconductor lasers can involve considerations such as the presence of strip-type resistance regions in the current-carrying layer. Overall, these parameters play a crucial role in understanding and improving the performance of semiconductor lasers for various applications.
What are the methods to measure the intrinsic quality factor of a ring resonator?5 answersThere are several methods to measure the intrinsic quality factor (Q-factor) of a ring resonator. One approach is to use a general Q-factor measurement system that includes excitation of the resonator, acquisition of the resulting signal, and signal processing to determine the Q-factor. This method allows for measurements in the frequency domain, time-frequency domain, or time domain, with each approach having its own advantages and limitations. Another method involves using thermoelastic dissipation (TED) to control the Q-factor of a resonator. By carefully designing the resonator and trimming the heat conduction path, the Q-factor can be modified while minimizing changes to the resonance frequency. Additionally, the use of a ring electrode in a quartz crystal microbalance (QCM) resonator has been shown to result in a high Q-factor and good frequency stability.
What are the recommended criteria to determine the intrinsic measurement inventory appropriateness in different situations?5 answersThe recommended criteria to determine the intrinsic measurement inventory appropriateness in different situations include classification schemes, inventory policy, policy selection methods, and multi-criteria situations. Gupta et al. propose a classification of inventory selection parameters/criteria, including 21 parameters divided into three levels, to estimate the optimal inventory level. Rezaei and Dowlatshahi design a rule-based method that considers multi-criteria situations and inherent ambiguities in the reasoning process of inventory classification. Muna et al. emphasize the importance of selecting a reliable method of gaining access to information to minimize negative effects on business variability, size, and risk.

Alscher and Schneider discuss the existence of three objectives in inventory decision-making, including service-level, number of replenishment, and mean stock on hand, and propose a method to choose an efficient solution.
What is the best way to measure quality standards?5 answersThe best way to measure quality standards is through the use of standardized metrics and assessment frameworks. These metrics and frameworks provide objective criteria for evaluating conformance to standards and assessing the quality of various domains, such as healthcare, geospatial data, parks and outdoor recreation, and higher education institutions. For example, in the healthcare domain, clinical document interchange standards have been used to calculate and report care quality based on aggregated data from multiple electronic health records. In the geospatial data domain, geospatial linked data quality metrics have been developed specifically to evaluate conformance to standards. Visual research methods have also been adapted to measure standards of quality for parks and outdoor recreation. Additionally, accreditation processes have been implemented in higher education institutions to ensure quality maintenance. Overall, the use of standardized metrics and assessment frameworks tailored to specific domains is crucial for effectively measuring quality standards.
