Electromagnetic Scattering from Dielectrically Coated Axisymmetric Objects Using the Generalized Point-Matching Technique (GPMT)

Abstract

In Part I, the theoretical formulation of a numerical solution to electromagnetic scattering problems encompassing arbitrarily oriented, three-dimensional axisymmetric perfectly conducting or dielectric objects embedded in an axisymmetric dielectric obstacle has been developed in a form suitable for an efficient computer solution. Here, numerical results for a wide variety of scatterer configurations are presented in order to demonstrate the validity and accuracy of our generalized point-matching technique formulation. Whenever possible, the Mie theory, the extended Mie theory, the homogeneous extended boundary-condition method (EBCM), the multilayered EBCM, and the Rayleigh-Gans-Debye approximation have been used in the process of examining the applicability of the suggested method. In all of the cases considered, excellent agreement has been achieved.
