Abstract: In this research, we will propose an efficient FDTD (Finite-difference time-domain) calculation method in low frequency range such as kHz or MHz frequency range. This method utilize transfer function which is modeled by rational function. The transfer function is calculated by the ARMA (Autoregressive moving average model) algorithm to reduce calculation time. The effectiveness of the proposed method is confirmed by calculating EMF of steady state is excited in layered dielectric in the vicinity of the WPT (Wireless Power Transfer) system.
