Efficiency Enhancement of Wireless Power Transfer Localization using Defected Metasurface

This paper presents a defected metasurface for efficiency enhancement of wireless power transfer localization. To examine this study, the WPT system composes of large Tx small Rx and 5x5 metasurface, which is designed at the operating frequency of 13.56 MHz. Simulated results show that the efficiency of WPT with defected metasurface of 38% when the Rx is placed at the corner unit cell metasurface. Such efficiency result equal the uniform metasurface case with Rx at center.
