Karazin popup.description2 The object of research are processes of forming of electromagnetic fields with defined temporal, spatial, energy and polarization characteristics by complex electrodynamic structures that contain multi-element, multiresonance system components (including impedance surfaces) with different geometrical, electrophysical parameters and arbitrary topology of radiating elements. The aim is to develop numerical and analytical methods for solving boundary value problems of electrodynamics for radiator systems of electric and magnetic types, located in the waveguides and electrodynamic volumes with perfect conductive and impedance surfaces; creation of mathematical models of multi-element, multiresonance, combined radiating structures with impedance vibrators and slot elements; carrying out multi-parameter simulation concerning determination of the physical properties of the diffraction fields of structures and the creation of SHF and EHF radiating devices with new and advanced features for different applications, such as military and industrial applications. In the work carried out comprehensive (theoretical and experimental) studies to identify new physical laws governing the formation of the spatial, energy, space-time, frequency and polarization characteristics of the electromagnetic fields of the combined magnetic-electric radiating structures in electrodynamic volumes with perfectly conductive and impedance boundaries. Scientific novelty consists in obtaining new scientific knowledge concerning the definition of new physical effects and patterns in the propagation of electromagnetic waves and the formation of the spatial distribution of the diffracted field in the complex electrodynamic structures and volumes with combined multi-element structures of the magnetic-electric type.
