Abstract:

In this paper, wireless power transfer based on resonant coupling with metamaterials is studied. We show with numerical studies that the coupling between transmitter and receiver can be enhanced, and the power transfer efficiency can be improved by metamaterials. A prototype wireless power transfer system and a metamaterial is designed and built. Experiment results prove the efficiency improvement with the fabricated metamaterial. The system with metamaterial is capable of transferring power wirelessly at roughly double the efficiency of the same system without a metamaterial.
