Paper Abstract

By using a new numerical method based on the extinction theorem boundary condition. we obtain scattered intensities from both random and periodic perfectly conductive rough surfaces. Lambertian scattering and enhanced backscattering are predicted for random surfaces having Normal statistics and a Gaussian correlation function. Differences between distributions of scattered intensities for T.E. and T.M. waves are studied. Also, the behaviour of the backscattering peak with λ and θ0 is discussed. We show as well that, the blaze effect for the antispecular order, obtained from deep reflection gratings with arbitrary profiles, is closely connected with the effect of enhanced backscattering observed in random rough surfaces. In addition, we prove that when the illuminated structure has a center of symmetry, the intensity in the specular direction is also enhanced.
