Abstract
We present an efficient scheme for the analysis of electromagnetic scattering from target and environment composite model. In this scheme, the whole computed domain is divided into a target part and an environment part, and each part is formulated by different integral equations. The two parts are solved one by one until the relative residual error is less than a given value. Compared with conventional solution with pure electric field integral equation (EFIE), the proposed scheme has a better convergence and lower memory requirement. Additionally, the multilevel fast multipole algorithm (MLFMA) is utilized to accelerate the computations of matrix vector product. Simulated radar-cross-section (RCS) results of several examples demonstrate its validity and efficiency.
