“…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.…”

“…However, for non-normal incidence, the patterns do show less symmetry, as expected, and an even richer and more complicated angular structure. In principle, the enhanced backscattering peak phenomenon should exist in both coand cross-polarized scattering [17,18,19]. However, for the roughness parameters assumed in this work, one observes instead of a well-pronounced peak in the backscattering direction, a ridge of constant enhanced intensity in parts of the backscattering plane (q In passing, we note that having available only the inplane and out-of-plane results for the same angle of incidence, the local enhancements observed in e.g.…”

Scattering of electromagnetic waves from two-dimensional randomly rough perfectly conducting surfaces: The full angular intensity distribution

2010

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.

“…Previous analysis of optical disk memories and other random or rough surfaces has typically described the incident field as a plane wave. [1][2][3][4][5][6] As the numerical aperture of the incident light increases, as is the case for the new digital video disk (DVD) format, this approximation becomes less satisfactory.…”

We have developed a numerical diffraction tool for cases in which the incident field is a focused spot and the diffracting structure is a single structure or an aperiodic surface. Our approach uses the integral formulation to solve Maxwell's equations and is different from previously published methods in its choice of basis function. We compared numerical results with experimental measurements of the far-field intensity for a focused spot incident on an aluminum grating, and the comparison was favorable. Finally, we predict the diffraction behavior of the proposed digital video disk format for the next generation of optical disk. Our analysis shows that the reflected signal for this format has a strong dependence on the polarization of the incident light.
