Polarization of light scattered from slightly rough dielectric film

We found that a slightly rough thin dielectric film polarizes diffusely scattered light. There is a discrete set of angles of incidence and observation for which the intensity of a nonspecular diffuse P-polarized component is significantly greater than that for S polarization.

Satellite peaks in the scattering of p-polarized light from a randomly rough film on a perfectly conducting substrate

Abstract The diffuse scattering of p-polarized light from a one-dimensional, randomly rough dielectric film deposited on a planar, perfectly conducting surface is studied by means of small-amplitude perturbation theory. The dielectric constant ed and the thickness d of the dielectric film are chosen in such a way that in the absence of roughness the scattering system supports N (≥ 2) guided modes whose wavenumbers are q 1 (ω), …,q N(ω) at the frequency ω of the light incident at an angle θo. We investigate the occurrence of satellite peaks, in addition to the enhanced back-scattering peak, in the angular distribution of the intensity of the diffusely scattered light, at angles θs(n, m) given by sin θs(n, m)= − sin θ0± (c/ω) [Qn(ω) − qm(ω)] for n, m=1, …, N(n ≠ m). These satellite peaks are multiple-scattering effects due to degenerate timereversal symmetry.

Wave scattering from a bounded medium with disorder

Abstract We study theoretically the angular distribution of the intensity of waves reflected from a slab with surface or volume random scatterers in the case when the thickness of the slab is small in comparison to the mean free path. We predict the existence of enhanced scattering peaks in some special directions caused by “degenerate time-reversal symmetry” in a bounded system with a discrete spectrum.
