Scattering of electromagnetic waves at edge of semiinfinite dielectric layer embedded in ideally conducting halfspace
Abstract
The problem of diffraction and scattering of electromagnetic waves in the quasioptical range is solved for the model of a semiinfinite dielectric layer embedded in a metal occupying a half space. The fundamental integral equations are derived with the aid of appropriate Green functions for the two regions, with the dielectric layer assumed to fill a planeparallel waveguide. This system of equations is solved numerically by the KrylovBogolyubov method, first using the general algorithm of this method and then using the much faster algorithm based on representation of the kernels by a series of exponential functions. The diffraction coefficients and the cross section for scattering obtained as a result can serve as a basis for calculations pertaining to partly coated metal objects and their wave scattering characteristics, also for error analysis of various approximate methods of calculation. Twoposition diagrams of effective scattering cross sections were calculated on a YeS1033 Unified System computer for three different angles of incidence.
