Modeling the scattering from a dielectric spheroid by a system of dielectric spheres

Abstract

The solution to the problem of electromagnetic waves scattering by an array of spheres is used to simulate the scattering by a spheroid. The scattering by an array of spheres is formulated by expressing the incident, transmitted, and scattered fields in terms of the vector spherical wave functions, and the boundary conditions are satisfied by applying the translation addition theorem for the vector spherical wave functions. The advantage of using the proposed technique is the simplicity and efficiency in computation. The modeling of a conducting or dielectric spheroid is outlined and numerical results are presented graphically and compared with those based on other available methods to show the validity of the analysis.
