Multi-GPU HIE-FDTD method for the solution of large scale electromagnetic problems

In this paper, Multi-GPU hybrid implicit-explicit finite-difference time-domain (HIE-FDTD) method is proposed for the solution of large-scale electromagnetic problems. The HIE-FDTD method is one of the weakly conditionally stable algorithms which can use a larger time step size than that for the conventional FDTD method. Furthermore, the HIE-FDTD method is suitable for parallel computing because this method requires only the local matrix operations. First, the HIE-FDTD method is reviewed briefly. Second, the proposed method is described for the efficient electromagnetic field simulation. Finally, the efficiency of the proposed method is evaluated by some numerical results.
