Abstract

The periodic structure can be analyzed by using the split-field FDTD method. But when the very fine grid is involved, more memory and time are required, sometimes it even canpsilat be calculated on single PC machine. In this paper we present the parallel implementation of the split-field FDTD method based on the message passing interface(MPI), which solves the memory and speed problems, and give out a new method based on the conversation of energy, so as to verify the accuracy and the efficiency. We also compare the results of the serial split-field method with the proposed method.
