Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, wireless sensor networks (WSNs) have been implemented in the manufacturing industry.Nevertheless, a notable challenge in WSNs lies in the requirement for regular battery replacement.To address this issue, we have proposed a power supply system using Cavity Resonance-enabled Wireless Power Transfer (CR-WPT).The utilization of higher-order modes, in contrast to the commonly studied predominant resonance modes, offers increased flexibility in adjusting power transmission frequencies.In this report, the cavity was accurately simulated using electromagnetic field analysis software,the output impedance was obtained analytically; a matching circuit with simultaneous 2-port matching was designed.Consequently, the RF-RF efficiency of 34.0 % was achieved.With the conventional design at 14.6 %, a 2.3-fold improvement has been achieved.
