In this paper a parallel algorithm is created for solving electromagnetic wave scattering problems. The algorithm based on the finite difference time-domain (FDTD) representation of the Maxwell's equations written in 3L Parallel Fortran for use on a transputer array. The problem simulated consists

## Abstract A new method to reduce the numerical dispersion of the conventional alternatingβdirectionβimplicit finiteβdifference timeβdomain (ADIβFDTD) method is proposed. First, the numerical formulations are modified with the artificial anisotropy, and the numerical dispersion relation is derived
