Description
Summary:The wireless power transfer system using a magnetic resonance developed in 2007 was very useful and expectable. The use of the superconducting coil was suggested to improve the efficiency of the magnetic resonance system, and the increase in the quality factor was confirmed. The reflection coefficient of Sparameter (S 11 ) was analyzed under the mixed use of the superconducting coil and the normal conductor coil in this study, as the mixed use of both coils is inevitable in actual applications. As a result, the transmission efficiency was increased by the application of the superconducting coil due to the coil's high energy storage.
