Paper Abstract

On the basis of a recently established dyadic Green's function formalism describing the diffuse scattering of light from a rough surface, we investigate the fundamental integral equation describing, selfconsistently, the electromagnetic field in the selvedge, i.e. profile, region. With emphasis on the physical properties, a detailed description is given of the Green's function which by screened radiation couples the different external current density sources in the profile together. Numerical calculations showing the electromagnetic radiation in the plane of a flat surface stemming from an oscillating dipole just outside the surface are presented. Finally, a few remarks are presented concerning the determination of the selvedge field associated with a so-called strip geometry of the surface topography.
