In this paper, simple modifications to the pseudospectral time‐domain (PSTD) algorithm that offer dispersion compensation are presented. In a homogeneous lossless medium, the compensation offers an exact solution for one‐dimensional (1D) propagation. For 2D and 3D propagation, the proposed method can compensate dispersion for a central frequency in any direction. The techniques are then extended to inhomogeneous materials containing piecewise constant electromagnetic properties and are shown to offer dispersion compensation. © 2004 Wiley Periodicals, Inc.
