Backscattering of Electromagnetic Waves from a Slightly Rough Surface with a Lossy Layer.

摘要

The purpose of this report is to analyze the problem of electromagnetic wave scattering from a layer which is rough on both sides. A general vector theory is developed for horizontal and vertical polarizations in which use is made of the Fourier transform and the small perturbation theory. Although there has been a great deal of work performed in the area of electromagnetic wave scattering from plane-layered media, there has been very little work on the problem of wave scattering from a layer which has both interfaces rough. A solution to this problem is important if one is interested in such things as radar scattering from a layered road surface or from a terrain surface covered with ice. There are many other applications in which a solution to this problem would be of great aid.
