The investigation methods are rigorous modified method of the Riemann-Hilbert problem, Levine-Malin's techniques modified Fourier method and experimental investigation technique of MDS of coaxial species. Rigorous algorithms and calculation programs of MDS spectrum in gyrotropic media are developed. Dispersion properties of transmission line of new type are considered. Computer aided design of RF filter based on coaxial resonators of complex shape is carried out. By experimental investigations of one-link band-pass filter the results of this modeling were used. The obtained results can be used for filter on DR designing with reducing weigt and dimensions in several times compared with traditional constructions.
