Electromagnetic Scattering by a Conducting Sphere with Anisotropic Coating

The electromagnetic (EM) scattering by a conducting sphere with anisotropic coating is investigated. A surface-volume integral equation (SVIE) method is developed, in combination with Dini series expansion (DSE). Appropriate orthogonal sets of spherical vector wave functions (SVWFs) are employed that directly satisfy the boundary conditions on the conductor's surface, and allow the transformation of the SVIEs to a simple algebraic system. The validity of the developed method is examined and numerous radar cross section (RCS) computations are performed.
