Investigation on the characteristics of electromagnetic scattering from 2-D fBm rough surface of layered medium

TL;DRAbstract

The electromagnetic scattering from the rough surface of layered medium with plane wave incidence is investigated. A 2-D fBm fractal rough surface is used to simulate the natural rough surface of layered medium, and the formulae of the scattering coefficient of the 2-D fBm fractal dielectric rough surface of layered medium with the plane wave incidence is derived by using the small perturbation method in association with the power spectrum density of 2-D fBm fractal rough surface. The angular distribution of the bistatic-scattering coefficient of HH polarization are obtained by numerical computation, the influence of fractal dimension, the permittivity of substrate medium, the permittivity and the mean layer thickness of intermediate medium, the surface roughness parameters and the frequency of the incident wave on the bistatic-scattering coefficient is discussed. The fractal characteristics, the basic characteristics, the zonal characteristics and the characteristics with varying freq
