Study of a 3DMLUV-FIA method for EM scattering from dielectric object and rough surface

Abstract

The electromagnetic scattering from the composite model of a three-dimensional (3-D) dielectric object located above a two-dimensional (2-D) dielectric rough surface is analyzed in this work. The 3DMLUV has been successfully applied in the scattering of PEC targets, however, when the object or rough surface become dielectric, the coupling between dielectric object and dielectric rough surface will lead to slow constriction. The FIA is applied to further speed up the constricted speed of the matrix required in 3DMLUV. The efficiency, stability and accuracy of the proposed method are demonstrated in a variety of scattering problems.
