Abstract

We describe a domain decomposition strategy based on the combination of linear embedding via Green´s operators (LEGO) and an electric-field integral equation (EFIE) for solving radiating conducting elements in the presence of anisotropic media. Furthermore, in order to facilitate the inversion of the LEGO surface integral equation we employ the eigencurrents expansion method (EEM) to generate local entire-domain basis functions on the boundary of each LEGO sub-domain. Through a few selected numerical examples we discuss the accuracy of the overall approach and the convergence properties of the EEM.
