Abstract

A weakly conditionally stable (WCS) finite-different time-domain (FDTD) algorithm is presented for resonant cavity analysis. The time-step in the WCS-FDTD is based on the largest cell size. And compared with the alternating-direction implicit (ADI) FDTD, the WCS-FDTD method is of higher accuracy and efficiency. Numerical results indicate that the CPU time for the WCS-FDTD method can reduced to about two-thirds of that for the ADI-FDTD scheme.
