Karazin Kharkiv National University popup.description2  Object of research - processes of formation of electromagnetic fields with certain frequency, space-energy and polarization characteristics, complex electrodynamic structures containing multi-element, multi-resonant, and low-quality (ultra-wideband) system components (including impedance) with different geometric, electric parameters and an arbitrary topology of their radiating elements. The aim of the research is further development of numerical-analytical methods for solving boundary value problems of electrodynamics for systems of radiations of electric and magnetic types, located in waveguide paths of different types and types and in electrodynamic volumes with perfectly conducting and impedance surfaces; construction on their basis of mathematical models of multi-element, multi-resonant, combined radiating structures with impedance vibrating and slot elements, waveguide-resonator-slot structures with local dielectric and metal-dielectric inclusions and impedance boundary surfaces. Based on the solutions of the boundary problems of electrodynamics obtained in this report, mathematical models were created for the first time: systems of impedance monopoles in a rectangular waveguide, systems of impedance monopolies on a spherical surface, waveguide-slot array on a waveguide with multilayer filling, of a slot radiator in a waveguide filled with an anisotropic dielectric with longitudinal anisotropy, frequency-selective metasurfaces that support the locked mode. Programs for calculation of electrodynamic characteristics of magnetoelectric radiating structures are developed. Studies of the electrodynamic characteristics of the system of impedance monopoles in a rectangular waveguide, the system of impedance monopolies on a spherical surface, frequency and time characteristics of radiation of ultra-wideband vibrator-slоt structure of the Klevin type.
