Numerical Simulations and Analysis of Electromagnetic Scattering from a PEC Target below a Two-layered Dielectric Rough Surfaces: Vertical Polarization

摘要

To analyze the properties of the electromagnetic (EM) scattering from a target located below a two-layered rough surfaces, the method of moments (MOM) is introduced in this paper. The incident wave is considered in the vertical polarization. The discrepancies of EM scattering from this composite model and two-layered rough surfaces only are shown firstly. Emphasis is put on discussing the influences of cylinder and surface parameters, such as the radius and altitude of the cylinder, the root mean square (rms) height and correlation length of the Gaussian rough surfaces on the bistatic scattering coefficient.
