Scattering of a Gaussian Beam by a Conducting Spheroidal Particle With Non-Confocal Dielectric Coating

A semi-analytic solution to the Gaussian beam scattering by a conducting spheroidal particle with non-confocal dielectric coating is obtained within the framework of the generalized Lorenz-Mie theory (GLMT). By virtue of a transformation between spheroidal and spherical vector wave functions, a theoretical procedure is developed to deal with the non-confocal boundary conditions. Numerical results of the normalized differential scattering cross section are evaluated for coated spheroidal particles.
