Popis:	This report summarizes the principal results in three areas of investigation. The first is a new full wave method that takes two dimensional surface roughness into account and does not use the telegraphist's equations. The second study concerns scattering from a rough surface when the incident field is a gaussian beam. The third is a summary of the difficulties inherent in Bahar's extended full wave theory on which the prediction of enhanced backscatter was based. It was found that enhanced backscatter occurred only because of the invalid assumption that the heights and slopes were uncorrelated.
