Efficient Solutions of Volume Integral Equations with Inhomogeneous Materials
Volume integral equations(VIEs)are essential and indispensable for solving inhomogeneous electromagnetic problems by integral equation approach.Traditionally,the VIEs are solved by the method of moments(MoM)with the Schaubert-Wilton-Glisson(SWG)basis function.The SWG basis function requires conformal meshes in geometric discretization and may be inconvenient for inhomogeneous problems.In this work,we propose a Nystr(o)m-like scheme for solving the VIEs.The scheme chooses some representative discrete nodes in each tetrahedral element and uses a point-matching procedure to transform the VIEs into matrix equations.The scheme can allow an inhomogeneity of materials in each tetrahedron and may simplify the geometric discretization.A numerical example for electromagnetic scattering by a multilayered dielectric object illustrates the effectiveness of the scheme.
