Karazin popup.description2 The object of research - the physical processes occurring in the excitation, emission and scattering of the primary electromagnetic fields by slotted and wire inhomogeneities with arbitrary geometry, impedance and electrical parameters in the waveguides with dielectric inclusions and impedance dipoles and monopoles above a curved surface. The purpose of research - the identification of the physical properties of the electromagnetic field generated in the complicated structures (with a complex boundary of ideal conductivity or impedance surface, structures including magnitodiehlektric or wire heterogeneity), and carrying out theoretical and experimental research. Methods: classical methods of field theory based on Maxwell's equations, asymptotic averaging method, modified method of eigen waves (research developed by the authors); method of small parameter; methods of induced EMF, MMF and EMMF (modified by the authors) for studying the electromagnetic characteristics of individual vibrators and slots; the Galerkin method of moments. For the first time proposed and theoretically justified: 1. A new method for irradiating a material medium by ultrahigh frequency field using a resonant slot in the end wall of a rectangular waveguide with a local dielectric insert within the waveguide near the slot 2. A way to intense heating with the microwave field is found for small dissipative objects by inserting them into a resonant slot in the diaphragm in a rectangular waveguide. It is proposed to determine their dielectric constant and loss coefficient carrying out special measurements and calculations. 3. The possibility of coupling of adjacent electrodynamics volumes via fine-wire segments running through the waveguide wall without any contact with it is confirmed by carrying out the experiments and calculations 4. On the basis of the computational algorithms developed by the project authors it was found that the impedance affects the shape of the pattern of radial vibrator, located on the sphere. By changing the impedance at the sphere of resonance size the main lobe maximum of the antenna can be scanned in angular sector [ ]. Product Description popup.authors Блинова Н. Ляховський А.
