Abstract: The finite-difference time-domain (FDTD) algorithm is employed to simulate microwave pulse coupling into narrow slots which have depths much narrower than on FDTD cell.It analyzes the parallelism of FDTD algorithm and presents a parallel algorithm of simulation.In order to reduce the communication time, it also uses the message fusion and the lap of computation and communication.In addition it analyzs the complex of the parallel algorithm and gives some results on the Alpha workstation.

Key words: finite-difference time-domain (FDTD) algorithm, microwave pulse, coupling into narrow slots, parallel computing
