In this work fluctuations in the electric field of surface plasmon polaritons undergoing random scattering on a rough metallic surface are considered. A rigorous closed form analytic expression is derived describing second order correlations in the resulting plasmon speckle pattern assuming statistically stationary and isotropic roughness. Partially coherent planar Schell-model source fields can also be described within the developed framework. Behaviour of the three-dimensional degree of cross… Expand

Speckle correlation functions applied to surface plasmons
The optical intensity transmitted through a random pattern of subwavelength holes in a metal film exhibits a speckle pattern. We study the variation of this speckle pattern as a function ofExpand
Near-Field Effects in Spatial Coherence of Thermal Sources

Degree of polarization in near fields of thermal sources: effects of surface waves.
TLDR
The concept of degree of polarization for electromagnetic near fields, based on the generalized Stokes parameters that appear as expansion coefficients of the 3 x 3 coherence matrix in terms of the Gell-Mann matrices, is introduced. Expand

Spatial correlations in the near field of random media.
TLDR
It is shown that the spatial correlations of optical fields in close proximity of highly scattering, randomly inhomogeneous media depend on this distance and, moreover, their extent can be significantly smaller than the wavelength. Expand
