This volume presents up-to-date surveys of many aspects of rough surface scattering that are relevant to the scattering of electromagnetic waves from surfaces with nanoscale roughness. Both the direct and inverse scattering problems are considered, perturbative and computational approaches to their solution are described, and experimental methods and results are discussed.

Zusammenfassung
All real surfaces, both those occurring naturally, and those fabricated artificially and with great care, are rough to some degree. It is therefore of interest, and often of importance, to know the extent to which this roughness affects physical p- cesses occurring at a surface. A particularly interesting class of physical processes occurring at a rough surface is the scattering of electromagnetic waves from it, or their transmission through it. In this case the degree of the surface roughness is referred to the wavelength of the waves incident on it. The study of the scattering of electromagnetic waves from rough surfaces has been actively carried out for more than a century now, since Rayleigh's inves- gations of the scattering of a monochromatic plane wave incident normally on a 1 sinusoidal interface between two different media. The first theoretical treatment of the scattering of an electromagnetic wave from a randomly rough surface was due to Mandel'shtam/ in the context of the scattering of light from a liquid s- face. In these pioneering studies the angular dependence of the intensity of the scattered field was calculated by perturbation theory as an expansion in powers of the surface profile function though the first nonzero term, a single scattering approximation.
