The results of this work are: proposed models of multisectional systems of frequency and mode filtration, models of absorbtion of electromagnetic waves in open and closed transmission line of UHF band; generelezation of methods of circuits and matrix functions for researching two-mode regime in waveguide and over complicated structure of base element; devices of limitted periodic sets.
