Electromagnetic scattering of an arbitrary plane wave from a spherical shell with a circular aperture
The problem of the scattering of an electromagnetic plane wave with arbitrary polarization and angle of incidence from a perfectly conducting spherical shell with a circular aperture is solved with a generalized dual series approach. This canonical problem encompasses coupling to an open spherical cavity and scattering from a spherical reflector. In contrast to the closed sphere problem, the electromagnetic boundary conditions couple the TE and TM modes. A pseudodecoupling of the resultant dual series equations system into dual series problems for the TE and TM modal coefficients is accomplished by introducing terms that are proportional to the associated Legendre functions P/sup -//sup m//sub 0/. The solutions of the TE and TM dual series problems require the further introduction of terms proportional to P/sup -//sup m//sub n/, where 0less than or equal ton
