Abstract

A method to calculate the effect of double interaction between edges and plane facets is presented. The calculation is made by combining the equivalent currents method and geometrical optics. The results are well suited to be added at the physical optics fields scattered by plane facets. The scheme is efficient for programming on computers together with a facets-edges model of electrically large targets. A comparison with data from a numerical scheme for obtaining the scattered field of three-dimensional bodies using the CG-FFT (conjugate-gradient and fast Fourier transform) method is presented.<>
