Polarimetric Characterization of Magnetic Flat Dipole Embedded in Multilayer Structures

The scattering properties of an embedded planar magnetic dipole are addressed in this paper. In order to obtain the scattered fields the method of moments in spectral domain is applied. The dipole scattering is characterized by the radar cross section (RCS), the polarimetric response and the alpha-angle from Cloude-Pottier´s target decomposition theorem. The results point out that alpha-angle is the most sensible parameter to variations on incident angles. The RCS is influenced by the incident angles and by the geometrical dipole area. The incident angles have also influence over polarimetric response, showing its use and interpretation must be done with extremely care.
