Abstract

A high-order solution of the electric field integral equation (EFIE) for penetrable inhomogeneous material volumes is presented. The solution is based on a high-order method of moment solution with a quadrature point-based discretization. It is shown that the solution leads to high-order convergence for the electromagnetic scattering by inhomogeneous dielectric scatterers. This is validated through the study of canonical scattering objects.
