Abstract

In this paper, a higher‐order alternative‐direction‐implicit (ADI) finite‐difference time‐domain (FDTD) method is presented. The dispersion analysis is performed and the results are compared with those derived from the regular ADI‐FDTD method. Based on the dispersion analysis, a guideline for choosing an appropriate time step in the ADI‐FDTD implementation is also developed. Both numerical simulation and dispersion analysis demonstrate the advantage of this higher order ADI‐FDTD method for improving accuracy. © 2003 Wiley Periodicals, Inc.
