A spectral-domain method for the electromagnetic scattering from a multilayered sphere buried in a stratified medium

In this work we present a rigorous method to analyze the electromagnetic scattering of an elliptically polarized plane wave by a multilayered sphere buried in a dielectric stratified medium (Fig. 1). The interaction of the electromagnetic radiation with the stratified material is taken into account by means of the transfer-matrix approach: in this way we can consider the stratified medium as an effective single interface. We assume that all media are linear and lossless.
