Fast fullwave simulation based on parallel-distributed HIE-FDTD method

Abstract

In this paper, parallel-distributed hybrid implicit-explicit finite-difference time-domain (HIE-FDTD) method is proposed for an efficient fullwave simulation of large-scale problems. The HIE-FDTD method is one of the weakly conditionally stable algorithms which can set a larger time step size than that for the conventional FDTD method. In addition, the HIE-FDTD method is suitable for parallel computing. First, the HIE-FDTD method is reviewed briefly. Second, the proposed method is described for the fast fullwave simulation. Finally, the efficiency of the proposed method is evaluated by performing computer simulations.
