Two-dimensional adaptive multiscale moment method for analysis of scattering from a perfectly conducting plate

Abstract

Two-dimensional adaptive multiscale moment method (AMMM) is presented for discussing the scattering from thin perfectly conducting plates. The EFIE is directly discretized based on the tensor product of the triangular basis by the Galerkin method. We present the formula of the linear equations for the two-dimensional multiscale basis. From one scale to another scale, the initial guess can be predicted according to the properties of the multiscale technique. AMMM can reduce automatically the size of the linear equation so as to improve the efficiency of the conventional moment method. Several numerical results are presented, which demonstrate that AMMM is a useful method to analyze the scattering problems from perfectly conducting plates.
