High frequency scattering analysis of dielectric surfaces: TM incidence case

Electromagnetic TM polarized plane wave scattering by dielectric surfaces is analyzed by high frequency asymptotic method. The scattering field is estimated from the equivalent currents induced by reflected plane wave on the dielectric surface. Effects of material nature, polarization and finiteness of the dielectric bodies are included in a multiple reflection coefficient. A comparison between theoretical estimations and measurement in the case of a rubber cube suggests a strong connection between the thickness of the body and its RCS values.
