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 of a space (air) where a spherical dielectric scatterer is located. This space is subdivided into fine equisize meshes extending throughout the 3‐D domain; the excitation wave is of sinusoidal form. Geometric decomposition is used as the principal algorithm strategy. Results are presented for the performance of the classical sequential algorithm and compared with the parallel algorithm in terms of computational speed‐up.
