Characteristic Mode Analysis of SCMR and CSCMR Systems

Abstract:

A Conventional Strongly Coupled Magnetic Reso-nance (CSCMR) system provides higher Power transfer efficiency and less sensitivity to misalignment compared to a traditional Strongly Coupled Magnetic Resonance (SCMR) system. This paper proposes, for the first time, a physical investigation of the SCMR and CSCMR systems based on the Theory Characteristic Modes. For both sytems, the high inductive nature of the coupling between the transmitting and the receiving units and the efficiency of the two configurations are drawn using the current distributions of the dominant mode, its intensity, and the high density of the magnetic flux lines in between.
