Abstract :
A high-order method of moment solution for the electromagnetic scattering by complex objects with composite materials is presented. The generalized technique can analyze material scattering by homogeneous and inhomogeneous material and conducting objects through both surface and volume equivalent currents. The solution employs high-order basis functions and a quadrature point-based discretization. It is shown that the solution leads to high-order convergence for the electromagnetic scattering by heterogeneous scatterers. This is validated here through the study of canonical scattering structures.
