Formal solution to the electromagnetic scattering by buried dielectric and metallic spheres

摘要: [1] The canonical problem of electromagnetic scattering by a buried dielectric or metallic sphere is studied in this paper. Two expansions are presented, which one the expansion vector plane waves into spherical waves. The other its converse, use two to facilitate matching boundary conditions at planar ground surface and surface. A general full-wave analytic solution given not only high-order multipoles but also multiple reflections between considered. Oblique wave vertical magnetic dipole considered as sources, though illumination can be arbitrary form with Weyl identity.
