|Abstract:||In this paper, an improved finite-difference time-domain (FDTD) algorithm is proposed in order to eliminate the restraint by the Courant-Friedrich-Levy condition. The new algorithm is developed based on an alternating-direction implicit (ADI) approach. In thismethod, the conventional time step is divided into two time sub-steps and each of their difference errors can be remedied. It thus has a high efficiency in the case when a long time is spent to reach a stable status, and this situation usually appears in periodical structures such as PBG structures. A numerical example of one-dimensional (ID) PBC materials is considered to demonstrate the availability and efficiency of this scheme. © 2003 Wiley Periodicals, Inc.|
