Electromagnetic Scattering from Turbulent Boundary Layers

Abstract

The incoherent scattering cross section of an underdense turbulent boundary layer adjacent to both a perfectly conducting ground plane and a perfectly conducting cylindrical surface is determined. It is found that the effect of the metallic surfaces on scattering from the turbulent plasma depends on the thickness of the boundary layer and the characteristics of the incident electromagnetic waves. For optically thin boundary layers, a plane metallic surface will enhance scattering in one linear polarization by up to 12 dB while eliminating scattering in the other polarization.
