Calculation of dispersion characteristics of regular waveguide with arbitrary dielectric filling with spectral method

Abstract

By the means of spectral method the universal algorithm of calculation of dispersion characteristics of regular waveguide with arbitrary dielectric filling is presented. The method is based upon presenting of guiding structures fields as serial expansion of some basis functions, having completeness and satisfying boundary conditions of waveguides boundary.
