pp: 536-540Evaluation of the Sacttering Matrix of Flat Dipoles Embedded in Multilayer StructuresSidnei J. S. Sant'Anna, José Carlos da Silva Lacava, and David Fernandes doi:10.2529/PIERS071219084227 Downloads: 645 Abstract:The expression for the scattering matrix of a dipole embedded in a multilayer planar structure is derived analytically. The structure is excited by an elliptically polarized plane wave incident at an oblique angle. Calculation of the electromagnetic fields present in a four-layer structure is performed in the spectral domain. The scattering matrices of electric and magnetic flat dipoles printed on the interface between two confined layers are evaluated using two polarimetric features.References:1. Lacava, J. C. S., A. V.
