基于磁准谐振耦合的无线按需供电技术

This article proposes and implements a novel magnetic quasi-resonant coupling (MQRC) scheme to realize the concept of energy-on-demand wireless power transfer (WPT). To prevent illegal receivers harvesting wireless energy, the proposed energy-on-demand technology nominates the authorized receiver to take over the initiative and generate a well-defended security key based on a two-dimensional frequ...
