Acceleration of large electromagnetic simulation including non-orthogonally aligned thin structures by using multi-GPU HIE/C-FDTD method

In this paper, multi-graphics processing units (GPU) hybrid implicit-explicit/conformal finite-difference time-domain (HIE/C-FDTD) method is proposed for the large efficient electromagnetic simulations. The HIE/C-FDTD method is constructed by combination of the HIE-FDTD method and the C-FDTD method. The HIE/C-FDTD method can adopt a larger time step size than that for the conventional FDTD method and can use the large cells. In addition, the HIE/C-FDTD method is suitable for parallel computing such as GPU Computing. First, the HIE/C-FDTD method is reviewed briefly. Next, the proposed method is described. Finally, the efficiency of the proposed method is verified by some numerical results.
