Abstract

We study the scattering of p-polarized light from a one-dimensional randomly rough metal surface that is periodic on average, rather than planar. We find that the contribution to the mean differential reflection coefficient from the diffuse component of the scattered light displays features, e.g., dips, at scattering angles θ_s given by sin θ_s = −sin θ₀ + n(λ/d), where θ₀ is the angle of incidence, n is a nonzero integer, λ is the wavelength of the incident light, and d is the period of the average surface, in addition to the enhanced backscattering peak at θ_s = −θ₀. These additional features are caused by the interference of each multiply scattered surface-plasmon polariton path with its time-reversed partner.
