Scattering by a Lossy Dielectric Wedge

손실 유전체 쐐기에 의한 산란

Rigorous formulation for solving the scattered fields by a lossy dielectric wedge is proposed. By employing the Kirchhoff's integrals in the physical domain and the extinction theorem in the mathematically complementary region, it is shown that the accurate solution is obtained by adding the numerically corrected fields generated by the multipole source expansions to the analytically approximated physical optics solution. Its accuracy is affirmed by the extinction behavior of the solution in the complementary region.
