Lowfrequency electromagnetic scattering theory for a multilayered scatterer
Abstract
The purpose of this paper is to present a systematic and integrated theory for the scattering of an electromagnetic wave by a multilayered scatterer. An integral representation for the electric field is constructed, and the normalized scattering amplitude is expressed in closed form. Representation for the scattering crosssection is also provided. Using lowfrequency techniques, the scattering problem is reduced to an iterative sequence of potential problems which can be solved successively in terms of expansions in appropriate harmonic functions. Expansions in low frequencies are given for the total field and the normalized scattering amplitude. The leading term of the normalized scattering amplitude and the scattering crosssection in the lowfrequency region are evaluated.
