Karazin popup.description2 The object of the study is the physical processes that occur during the excitation, radiation and scattering of primary electromagnetic fields by slot and wire inhomogeneities in waveguide tracts with dielectric inclusions and by impedance dipoles and monopoles over a impedance curvilinear surface. The purpose of the study is to detect the physical properties of an electromagnetic field formed in complicated structures (with complex boundary ideally conducting or impedance surfaces, structures including magnetodielectric, wire heterogeneity) by calculation studies performed on the basis of mathematical models constructed in the work, as well as experimental studies. Methods of research: classical methods of field theory based on Maxwell's equations, asymptotic averaging method, modified eigen-waves method (developed by the authors of the work); small parameter method; the methods of the electromotive, magnetomotive forces (modified by the authors of the work) for the study of the electrodynamic characteristics of single vibrators and slots; method of moments (Galerkin). For the first time the following is proposed and theoretically substantiated. New method of irradiation of the material medium by a field of ultrahigh frequency using a resonant slot in the end wall of a rectangular waveguide with a local inclusion in the form of a dielectric insert inside the waveguide. New method of intensive UHF field heating as well as determination of electrical parameters of small dissipative objects inserted into the resonance slot in the diaphragm of the rectangular waveguide. The possibility of connecting adjacent electrodynamic volumes with the help of thin-wire segments, which pierce the wall of a waveguide without contact with it, is confirmed. Also the slot coupling of two crossed waveguides with a dielectric plug in the region of coupling is studied. The regularities of radiation of a single slot and multielement slot systems in the surface of a rectangular waveguide with a slowing structure and a surface of an inhomogeneous coaxial line and vibrator radiators over a sphere which can be perfectly conductive or impedance one are studied. Expressions are obtained for own wave fields of a rectangular waveguide filled with anisotropic dielectric. Product Description popup.authors Бердник С. Блинова Н. Дахов В. Катрич В. Ляховський А.
