Save radar absorbing material by coating only around the edges of a target for reduced RCS

UTD (uniform theory of diffraction) analysis for scattering from a wedge with arbitrary two-face impedances was used to formulate the problem of EM scattering from a plate with rim loading for TE and TM polarizations. The corner effects are neglected, and the 2-D to 3-D field conversion is done by Siegel´s formula. An attempt is made to estimate the width of the coating around the edges, which would give about the same result as the plate when it is uniformly coated. The percent saving is thus estimated. Results are presented for monostatic cases, for many combinations of parameters.<>
