Abstract :
In this paper, bistatic RCS of objects coated with double-negative material (DNM) has been calculated by surface integral equations and MoM. The material is supposed to be homogeneous and isotropic. Based on Equivalent theory to deduce the Electric Field and Magnetic Field Integral Equation(EFIE/MFIE), then equations are translated into matrix equation by Galerkin method, equivalent electric current and magnetic current are achieved, then scattering field of coated objects can be calculated. The results of MoM for coated sphere are compared to results of Mie series analytic method. It is found that the results match well.
