Analysis on resonant frequency of thick-screen frequency selective surface
The 2010 IEEE International Conference on Information and Automation, 2010This paper designed a thick-screen frequency selective surface (FSS) having circle hole elements. Based on the moment method and using simulated computation, it is mainly investigated that the resonant frequency of thick-screen FSS with non-dielectric (circular hole element filling no dielectric) vs.

Frequency Domain Analysis Of Series Resonant Converters
TENCON '91. Region 10 International Conference on EC3-Energy, Computer, Communication and Control Systems, 2005The steady-state analysis of series resonant converters is presented using a frequency domain model. Generalized expressions for the resonant current and the capacitor voltage are derived. The possibility of multiple continuous conduction mode (MCM) when the power switches are supplied with continuous gate/base drive pulses is pointed out.

Application of Resonance Frequency Analysis in Orthodontics:A Review
Indian Journal of Public Health Research & Development, 2019The success of mini implants depends on primary stability followed by secondary stabilization. Resonance frequency analysis has been used to assess the primary stability of implants used in dentistry. There is a paucity in the literature regarding its use in orthodontics.

Research and analysis of frequency effect in magnetic resonance
2017 Chinese Automation Congress (CAC), 2017In the paper, a simple equivalent circuit model is built between transmitting coil and receiving coil via coupled magnetic resonance, and the simulation of frequency and efficiency is also supply. Node equations for the resonance coils are built by using the equivalent circuit and the optimum distance is analytically derived for optimum coupling ...

Numeric Analysis for Resonant Frequency of Rotating Blade
Applied Mechanics and Materials, 2009The paper implements numeric computation to analyze free vibration characteristics of rotating blade by the means of finite element method. The effects of rotate speed and temperature on the resonant frequency of blades are considered. The static frequency and the dynamic frequency under working speed for the room temperature and working temperature ...

Curvature and Resonance in Time-Frequency Analysis
In this thesis, we study singular integral operators that feature:1. Multi-linear behavior, i.e., the convolution is performed simultaneously on multiple inputfunctions over potentially different configurations;2. Carleson-type behavior, i.e., the defining object may be expressed as a supremum over a familyof integral operators with (generalized ...openaire +1 more source
Analysis of resonance frequencies and Q-factors of partially filled rectangular resonator
IEEE Antennas and Propagation Society International Symposium 1997. Digest, 2002When designing EM devices the problem of unwanted modes suppression arises. Dielectric absorbing insertion can be used to solve this problem. In this article the dependence of the fields resonance frequencies and the inherent Q-factor of the resonator from the location of a dielectric insertion and from its dielectric properties is analysed.

An Analysis of the Errors of Methods of Measuring Resonance Frequency
Measurement Techniques, 2014The factors that affect the errors of analog and digital methods of measuring resonance frequency are considered. Analytical expressions are obtained for the errors of each of these methods, taking the appropriate factors into account. The errors of the digital method are investigated numerically in the Matlab medium.
