Electromagnetic characteristics of simple targets embedded in chiral multilayer structures

The scattering properties of a chiral stratified multilayer structure having an printed planar electric 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, the α-angle from Cloude-Pottier's target decomposition theorem and the directivity function. The results point out that all parameters are sensible to variations on the chiral layer admittance. The chiral layer impinges a rotation on the polarization plane of linearly incident wave for all frequency analyzed.
