ABSTRACT
Basically two approaches have been employed for obtaining analytic solutions for scattering by a single particle. The first approach divides an entire space into separate refractive index regions. The second approach emanates from the integral equation formulation of the Maxwell equations. The rigorous theory of scattering by a homogeneous isotropic sphere is, therefore, widely referred to as the Mie theory. Numerical solutions constitute a very important part of the electromagnetic wave scattering solutions. A review of elastic light scattering theories and numerical methods can be found in Wriedt and Wriedt and Comeberg. Scrutinizing the scattering of electromagnetic waves by a uniformly charged metallic sphere, it was revealed that the scattering coefficients of a charged particle are different from those of an uncharged particle. The problem of scattering of electromagnetic waves by a single layer coated sphere was first solved by Aden and Kerker.
