Abstract

In this article, a new explicit finite-difference time-domain (FDTD) method is proposed to eliminate the Courant–Friedrich–Levy (CFL) condition restraint. This new algorithm is based on an alternating-direction explicit (ADE) method and Crank–Nicolson (CN) scheme. Called CN-ADE-FDTD method, and we present two versions of the proposed method. Numerical stability analysis of the new algorithm was also presented. Furthermore, the results by the CN-ADE-FDTD method are compared with the results by the conventional FDTD method. As a result, it is confirmed that the proposed method is unconditionally stable and superior to the conventional one. © 2011 Wiley Periodicals, Inc.
