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.

## Abstract An unsplit‐field perfectly matched layer (UPML) medium is introduced for higher‐order alternating direction implicit (ADI) formulation of the FDTD Method. By applying the proposed formulation, no field splitting is required for implementing higher‐order ADI‐FDTD PML; thus, the unconditi

## Abstract A new method to reduce the numerical dispersion of the conventional alternating‐direction‐implicit finite‐difference time‐domain (ADI‐FDTD) method is proposed. First, the numerical formulations are modified with the artificial anisotropy, and the numerical dispersion relation is derived

We consider a model explicit fourth-order staggered finite-difference method for the hyperbolic Maxwell's equations. Appropriate fourth-order accurate extrapolation and one-sided difference operators are derived in order to complete the scheme near metal boundaries and dielectric interfaces. An eige
