Abstract :
Radio equipment miniaturization requires reducing the dimensions of waveguide transmission lines. Lowering the frequencies enforces using the waveguides of more complicated cross-sections. Some results of the analysis of complicated waveguides are presented in the report. Some new designs of such a type waveguide have been proposed. For the waveguides, matrix operator based on MMT has been generated. It allowed to calculate their waveguide bases with required accuracy quickly.
