Karazin popup.description2 The subject of investigation is planar periodic and coaxial structures in gyrotropic medium. The purpose of this development work is making creation of packaged applied programs for research of oscillation and propagation of electromagnetic waves in metal-dielectric structures (MDS) located in gyrotropic media to design study of miniature microwave devices and measure of magnetized ferrites parameters. Research methods are the rigorous modified Riemann-Hilbert problem method, the singular integrated equation method (Levin - Malin's method), the modified Fourier's method and experimental methods of investigation of coaxial type MDS structures. The packaged applied programs for spectra of MDS in gyrotropic medium has been made. The dispersive properties of transmission line of new type are considered. A computer modeling of DR filters on the basis of coaxial resonators have been carried out. The results obtained can be applied for design study of DR filters with decrease of weight and sizes.
