The method is based upon presenting of diffracting structures fields as serial expansion of some basis functions, having completeness and satisfying boundary conditions of waveguides boundary.</p>spectral methodGalerkin methodarbitrary waveguidesспектральный методметод Галеркинадифракционные задачи
