Abstract :
Wireless energy transfer by coupled magnetic resonances is a popular technology in which energy can be transferred via coupled magnetic resonances in the non-radiative near-field. In this paper, we use coupled inductance model in circuit theory to analyze the power transfer efficiency of this technology, instead of using coupled mode theory (CMT). The analysis result is verified by some simulations and experiments.
