“…This we believe is the main reason for the reduced amplitude of the mean differential reflection coefficients in these cases relative to those of Fig. 2 [16,17,18,19]. However, the structures seen as peaks in the backscattering directions of the cross-polarized scattering, Fig.…”

By a computer simulation approach we study the scattering of p-or s-polarized light from a twodimensional, randomly rough, perfectly conducting surface. The pair of coupled inhomogeneous integral equations for two independent tangential components of the magnetic field on the surface are converted into matrix equations by the method of moments, which are then solved by the biconjugate gradient stabilized method. The solutions are used to calculate the mean differential reflection coefficient for given angles of incidence and specified polarizations of the incident and scattered fields. The full angular distribution of the intensity of the scattered light is obtained for strongly randomly rough surfaces by a rigorous computer simulation approach.

“…This is believed to be caused by the relatively large angle of incidence, for which it is known that coherent effects become weaker [16]. The CPU time spent on various stages of the calculations for one realization of the surface profile function and one angle of incidence.…”

“…In fact, the surface polariton propagates along the rough surface, then it is scattered into a volume wave due to the roughness, at the same time, a reverse partner exists with a path travelling in the opposite direction. These two paths can interfere constructively near the backscattering direction to produce a peak 17,18,19 . However, in one dimension 21 , this peak can only be observed for a (T M ) polarized incident wave because a surface polariton only exists for this polarization.…”

“…In the case of small-roughness metallic surfaces this peak was originaly explained by the infinite perturbation theory, 17,18,19 and further developments 21 have shown that the major contribution for the enhanced backscattering peak comes from the second order term in the field perturbation. However, in the one dimensional case the enhanced backscattering for a rough surface, appears only for a (T M ) incident wave due to the fact that plasmons polaritons only exist for this polarization.…”

“…In their method the field transmitted through the surface has been eliminated in such a way that the scattered field becomes a function of the incident field only. This reduced equation has been extensively used by Maradudin et al to study localization effects by a conducting surface, 17,18,19 coherent effects in reflection factor, 20 scattering by one-dimensional 21 and two-dimensional conducting surface. 22 It has to be noticed that the third order perturbation term was already explicited in the work of Ref.…”

The small perturbations method has been extensively used for waves scattering by rough surfaces. The standard method developped by Rice is difficult to apply when we consider second and third order of scattered fields as a function of the surface height. Calculations can be greatly simplified with the use of reduced Rayleigh equations, because one of the unknown fields can be eliminated. We derive a new set of four reduced equations for the scattering amplitudes, which are applied to the cases of a rough conducting surface, and to a slab where one of the boundary is a rough surface. As in the one-dimensional case, numerical simulations show the appearance of enhanced backscattering for these structures.

The incorporation of multiple scattering into theories of rough surface scattering has led to the prediction of a number of new effects, many of which have now been verified experimentally. Several of these new multiple‐scattering effects will be described in this paper, in particular the presence of satellite peaks in the angular dependence of light scattered from, or transmitted through, films whose illuminated surface is randomly rough; new features in the angular intensity correlation functions of light scattered from randomly rough metal surfaces, and surfaces that scatter light uniformly within a specified range of scattering angles, and produce no scattering outside this range. In addition, some suggestions for directions that research in the area of rough surface scattering could take in the next few years will be presented.
