Electromagnetic scattering from PEC object embedded between two dielectric rough interfaces

Electromagnetic (EM) scattering from perfect electric conductor (PEC) object embedded between two rough interfaces is investigated utilizing method of moments (MoM) for both TE and TM polarizations. Theoretical formulations of EM scattering model considered in this paper is presented and the total fields and their derivatives are solved numerically by employing MoM. The rough surfaces are modeled as realizations of a Gaussian random process with the Gaussian spectrum, while the tapered incident wave is chosen to reduce the truncation error. The influences of characteristic parameters of the rough surfaces, the relative permittivity of the medium, as well as the average height between the two rough surfaces, on the bistatic scattering coefficient (BSC) are discussed.
