GPGPU-based ADE-FDTD method for fast electromagnetic field simulation and its estimation

Yuta Inoue, Masaki Unno, Shuichi Aono, Hideki Asai

Abstract

In this paper, GPGPU(the general purpose computing on graphics processing units)-based ADE-FDTD (alternating-direction-explicit finite-difference time-domain) method is proposed for a massively parallel electromagnetic field simulation of large-scale problems. First, the ADE-FDTD method, which is an almost unconditionally stable algorithm, is described briefly. Next, implementation technique of the ADE-FDTD method on the GPGPU is shown. Finally, the efficiency of the GPGPU-based ADE-FDTD method is evaluated by performing computer simulations.
