Wireless Power using Magnetic Conductor

Abstract: In this paper, a wireless power transfer system (WPT) with magnetically coupled resonators is studied. The idea is to enhance the coupling coefficient and the transfer efficiency. Perfect magnetic conductor was used in numerical calculations in order to study the performance of a reflector. In the WPT system we studied, efficiency is increased from 48% without reflector to 72% with PMC reflector. With recently developed met material technologies, artificial PMCs can be designed and fabricated for such reflectors.
