Karazin popup.description2 Object to research - strip gratings in gyrotropic medium, strip and slot lines on anisotropic substrate and of a coaxial type metalodielectric structures. Purpose of the work - the development of bases of electrodynamics of periodic structures in gyrotropic medium, theoretical researches of propagation of electromagnetic waves in strip and slot lines for creation of their mathematical models and experimental research of a coaxial type metalodielectric structures. Methods of research - rigorous numerical - analytical modified methods of the Riemann - Hilbert problem and singular integral equations (Levin-Malin method) and experimental methods of a coaxial type metalodielectric structures. The rigorous algoritms and programs of calculation of spectras MDS in gyrotropic medium are created. The stands for experimental researches MDS of a coaxial type and breadboard models of filters are made in order to tune them in the required frequency. The received results will enable to develop filters on dielectric resonators of a meter range decreasing their volume and weigt in several times as compared with traditional designs.
