Karazin Kharkiv National University popup.description2  The object of research are the physical phenomena and processes of excitation, diffraction, scattering and formation of electromagnetic fields by electrodynamic structures with coordinate and piece-coordinate boundaries in a cylindrical coordinate system. The aim of the work is further development of the fundamental foundations of the electromagnetic field theory and the formation of fields according to their electrodynamic characteristics; development of numerical-analytical methods for solving limiting problems of electrodynamics for radiating structures with elements of electric and magnetic types, located in coaxial and round wave-shaped paths; construction of mathematical models of coaxial-slot radiating structures with ring and arc slot elements. At the first stage of the work, the distribution function of the equivalent magnetic current in the arc gap in the outer conductor of the coaxial waveguide was found by averaging; mathematical models of arc and ring coaxial-slot emitters in the outer conductor of a coaxial waveguide are constructed; formulas are obtained for the components of the tensor Green's function of a waveguide of complex cross section with piecewise coordinate boundaries in a cylindrical coordinate system.
