Abstract :
The opportunity of an effective usage of a stepped approximation for the calculation of cutoff frequencies and eigenfunctions of waveguides with complex cross-sections is shown. It is recognized that such an approach is productive for the analysis and optimization of polarizers based on sections of circular waveguides with rectangular ridges. The results of comparison with experimental data are represented.
