The Angular Intensity Correlation Functions $C^{(1)}$ and $C^{(10)}$ for the Scattering of S-Polarized Light from a One-Dimensional Randomly Rough Dielectric Surface

TL;DR

This paper introduces a new method to calculate short-range angular intensity correlation functions for s-polarized light scattering from a 1D random dielectric surface, revealing peaks linked to memory effects.

Contribution

It presents a novel approach to explicitly separate and compute the contributions $C^{(1)}$ and $C^{(10)}$ to the angular intensity correlation function.

Findings

$C^{(1)}$ shows peaks related to memory effects.

$C^{(10)}$ is a structureless function.

Peaks in $C^{(1)}$ arise from coherent interference of multiply-scattered waves.

Abstract

We calculate the short-range contributions $C^{(1)}$ and $C^{(10)}$ to the angular intensity correlation function for the scattering of s-polarized light from a one-dimensional random interface between two dielectric media. The calculations are carried out on the basis of a new approach that separates out explicitly the contributions $C^{(1)}$ a nd $C^{(10)}$ to the angular intensity correlation function. The contribution $C^{(1)}$ displays peaks associated with the memory effect and the reciprocal memory effect. In the case of a dielectric-dielectric interface, which does not support surface electromagnetic surface waves, these peaks arise from the co herent interference of multiply-scattered lateral waves supported by the in terface. The contribution $C^{(10)}$ is a structureless function of its arguments.
