Scattering by a conducting periodic surface with a rectangular groove profile Heath, James William
Abstract
The use of a periodic rectangular groove profile to eliminate specular reflection from a conducting surface is studied. The concentration of all scattered power in the principal backscatter mode, i.e., in a direction opposite to the incident wave, is possible under plane wave illumination if the period d = λ/(2sinθ₁): where θ₁. is the angle of incidence from the surface normal and A is the wavelength; and the width and depth of the grooves are properly chosen. An analytical and numerical study of the scattering is carried.out for arbitrary polarization to determine these groove dimensions and the effect of systematic errors in them. Experiments were performed at 35 GHz using brass plates of finite size under non-plane wave illumination. The experimental results show that the plates behave essentially as predicted.
