The aim of the research -development of the theoretical and numerical instruments for studies of the generalized electrodynamic processes in objects with boundaries in a Cartesian or cylindrical coordinate systems. Simulation and experimental study of the action and interaction of microwave radiation with the new electrodynamic systems, metamaterials, biological and organic environments. Methods of research - mathematical and numerical simulation and actual experiments. A completely new principle of construction of metamaterials with "giant" optical activity have been found and justified. A new (dihedral) oscillations in the open waveguide (gratin) resonators responsible for rotating the plane of polarization of the waves by plane-chiral structures were found. Effective algorithms of calculation of the main characteristics of the basic elements of the compressors, a rigorous model of active and passive compressor power were developed. A laboratory model of the microwave antenna of diffraction radiation with unique characteristics was developed. Concept of operating and lay-out of a radio interferometer self-oscillating type with fluctuation sensitivity not worse then 5*10^-3N was proposed and implemented. According to the project VLBI-2010 (Very Long Baseline Interferometry) a cryogenic receiving unit of a triple-band (S, X, Ka) irradiator have been investigated for the mirror antenna of radiotelescope. Differential cuvette based on the cylindrical waveguide, having a high sensitivity were proposed and investigated for the purpose of dielectrometry of high absorbed organic substances. Electrodynamic modeling of a sensor for measuring the complex dielectric permittivity (CDP) of biological objects has been carried out. The optimum configuration of the sensor allows reproducible measurements of biological liquids in trace amounts (5-6 µl) with an accuracy of not worse then +-2% of e' and e" . Measurements of CDP erythrocytes in clinical conditions made possible to establish the correlation between changes in CDP of red blood cells and biochemical reactivity of their membranes. Method for the diagnosis of chronic and acute coronary disorders at the cellular level has been proposed. By measuring CDP of red blood cells the effectiveness of EHF-autohemotherapy was confirmed. Studies on the action of EMR ( л =7.1 mm) in cells of the buccal epithelium of human in clinical conditions have shown the possibility of using buccal cells as a sensor of the severity of violations of cerebral circulation and effectiveness of EHF-autohemotherapy in the treatment of the aforementioned disorders.
