The investigation object are waveguides of complicated cross section planar 2D-periodical structures in gyrotropic medium and antenna system in magneyoacive plasma. The aim of this development work is theoretical investigation of oscillation and electromagnetic waves propagation in metal-dielectric structures located in gyrotropic media for design of small-sized microwave devices and measurement of magnetized up to saturation ferrites. The research methods are the rigorous analytical numerical modified Fourier's (MFM) method and the integral equations method. The theoretical investigation electromagnetic waves propagation in waveguides of complicated cross section has been carried out. The basis packaged applied programs for numerical and computer simulation both for external (periodical structures) and internal (waveguides of complicated cross section) electrodynamic problems has been developed. The caculation methods of transmission lines parameters on ferrite-dielectric substrate are presented. The results obtained can be applied for design study of DR filters with decrease weight and sizes.
