Abstract

The complementary operators method (COM) was developed for the purpose of canceling the reflections that arise from the artificial boundaries that terminate the computational domain in FDTD simulations. This article presents a discussion and an evaluation of COM. The theoretical background is developed in the analytical and discretized domains. Five numerical experiments are presented to show the effectiveness and high efficiency of COM. Applications to antenna radiation and absorbing boundary conditions are discussed
