Adaptive Fuzzy Modal Matching of Capacitive Micromachined Gyro Electrostatic Controlling
Sensors, 2023 A fuzzy PI controller was utilized to realize the modal matching between a driving and detecting model. A simulation model was built to study electrostatic decoupling controlling technology. The simulation results show that the modal matching can be gained by the fuzzy PI controller.

On Modal Excitation Using Capacitive Coupling Elements and Matching Network [PDF]
2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, 2019 A resonant characteristic mode (CM) is useful for antenna design if it is properly excited and well matched to the source. In this paper, we consider the feed design for the excitation of the fundamental CM of a rectangular chassis. The tradeoff between the required number of capacitive coupling elements (CCE) and matching elements used for achieving a

Capacitive-loaded interstitial antenna for perfect matching
Electronics Letters, 2003 A coaxial-cable capacitive-loaded interstitial antenna (CCIA) is proposed for 2.45 GHz. The capacitive load contributes to almost perfect matching and desirable heating area. The measured return loss of the CCIA is −28.377 dB, which may be considered as the best among those reported.

Design of Asymmetrical Relay Resonators for Maximum Efficiency of Wireless Power Transfer
International Journal of Antennas and Propagation, 2016 This paper presents a new design method of asymmetrical relay resonators for maximum wireless power transfer. A new design method for relay resonators is demanded because maximum power transfer efficiency (PTE) is not obtained at the resonant frequency ...
