| Abstract(in English) | The finite-difference time-domain (FDTD) method is a very useful numerical simulation technique for the electromagnetic field simulation. The Courant-Priedrich-Levy (CFL) condition must be satisfied when this method is used. Therefore, a huge computation time is needed for analyzing large-scale problems. In this paper, we propose a new FDTD method using the alternating-direction explicit (ADE) method for the efficient electromagnetic field simulation. This method is based on the ADE method which has been widely used as the explicit-type finite-difference algorithm for solving diffusion equations. It is possible to reduce from the sparse band matrix to the tri-diagonal matrix by introducing ADE method into one axis of 3-D space in the update algorithm, and the computation time can be reduced. We have called this new algorithm, which contains both of the explicit method and the implicit method, bi-directional semi-implicit (SI) FDTD method. Finally, the efficiency of the bi-directional SI-FDTD method is evaluated by computer simulations. |
