Sensitivity Analysis for the Lossless Dielectric Material in Wireless Power Transmission

In this paper, we propose the analysis of dielectric sensitivity of transmitting and receiving coils in wireless power transmission system. The diameter of the dielectric disk under test is defined using the diameter of the coil, the transmission distance and the distribution of the electromagnetic field along the virtual vertical axis. The proposed method for acquiring the dielectric sensitivity is applied to two representative coil models and the validation of this analysis is proved by the simulated results.
