Simulations and Experiments on Cubic Film Resonator for Wireless Energy Transfer System

In this paper, a novel resonator of wireless energy transfer system based on resonant coupling (WETRC) is studied. The cubic film resonator, consisting of copper strips on outer layer, which is separated by an insulation interlayer to copper sheets on inner layer, is fabricated. The relationship between resonant frequency and several key parameters of the resonator is analyzed using finite element method (FEM). Then the experiments have been carried out. Both simulation and experiment results show that the dielectric constant of interlayer and the length of inner copper sheet have significant influence on the resonant frequency of the system.
