Measurements of the hemispherical scattering distribution function of rough dielectric surfaces

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

“…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.…”

Monte Carlo simulation of Stokes vectors of polarized light scattering from two-dimensional random rough surfaces

“…In order to test the reliability of the algorithm, the numerical simulation results of our method were compared with numerical and experimental results of Chaikina et al [12], Knotts and O'Donnel [13] and Bruce [14]; good agreement with these results was achieved.…”

“…The main factors which lead to the scattering property are the statistical distribution of the local slopes [4]. The distribution profile of the Q component of scattered light is similar to the I component, which illustrates that there is almost no depolarization on the gold surface under weak rough conditions [12]. As shown in Figure 5, the distribution properties of the I, Q and U components of scattered light from a dielectric surface are similar to those from a gold surface.…”

Light Scattering from Randomly Rough Surfaces

“…These measurements correspond to scans along the horizontal and vertical directions, through the black dot in the center of the photographs of Figure 9. In subsequent work, the full hemispherical distribution was measured for metallic 29 and dielectric 30 surfaces. An example is shown in Figure 10.…”
