Abstract
In this paper, a new nonoverlapping domain decomposition (DD) scheme is built for solving EM scattering from penetrable targets. The Rao-Wilton-Glisson(RWG) basis functions are used to expand the equivalent surface electric/magnetic current on the entire surface. Each full RWG basis function across some boundary curve is split into two half-RWG basis functions. The global MoM matrix equation is then combined with the sparse matrix equation determined by the boundary electric/magnetic current continuity to form the complete model equation. In this DD scheme, when solving each subdomain, only part of the matrix needs to be stored into memory, and then the memory requirement is significantly reduced. Numerical examples are provided to demonstrate the validity of the proposed method.
