Experimental and Numerical Study of a Magnetic Resonance Wireless Power Transfer System Using Superconductor and Ferromagnetic Metamaterials

In this paper, a magnetic resonance wireless power transfer (WPT) system with two coils using superconductor and ferromagnetic (SC-FM) metamaterials was constructed and tested. SC-FM metamaterials were used in the WPT system to improve the transfer efficiency of the magnetic resonance WPT system. Three kinds of resonance coils were designed and the effects on the WPT system of different resonance coils using SC-FM metamaterials were investigated. This involved designing and conducting several kinds of WPT experiments with, and without, the SC-FM metamaterials. The results are then presented and analyzed. It is shown that the SC-FM metamaterials are able to improve the transfer efficiency of a WPT system.
