Abstract

The Rayleigh scattering from small circular holes in a thin screen was studied. The backscattered fields calculated from a dipole expansion were compared those from an exact solution and measurements for a single, electrically small hole. The backscatter from the holes is given by rather simple expansion where the first term is adequate for a good engineering solution. These expressions are within 1 dB of the exact solution for ka⩽0.96 for E-plane scattering and ka⩽0.69 for H-plane scattering when a is the hole´s radius and k is the propagation constant
