Nesterenko M. Excitation of electromagnetic fields by impedance vibrators and slot structures in electrodynamic volumes

The object of research is the processes of excitation, emission and scattering of electromagnetic fields. The purpose is the development of the theory of linear vibrator and slot radiators, creating a physically correct mathematical models and improved numerical and analytical methods for the solution of the boundary problems of electrodynamics to allow a theoretical analysis of the physical properties of electromagnetic fields and functional characteristics of single thin impedance vibrators with irregular geometric and electrophysical parameters, the narrow slots, as well as their multiple systems and combined dipole-slot structures located in various electrodynamic volumes, including those with impedance boundaries. The methods of integral equations, Green's function, averaging method, the method of successive iterations, expansion the unknown function in series of small parameter, methods of induced electromotive, magnetomotive and electro-magneto-motive forces, the method of moments were applied. The novelty consists in the further development of the theory of radiating structures, design and synthesis of a physically correct and mathematically rigorous numerical-analytical methods for solving the corresponding boundary value problems, including use in the methods of the induced EMF, MMF and EMMF of new adequate approximating functions for the distributions of currents found by an asymptotic method of averaging. The extent of application: the results are applied in the training process. The field of application: radiophysics and electronics.
