Gavva D. Wire antennas of the arbitrary configuration with nonlinear performances of a surface impedance

Object - the nonlinear effects in wire structures with nonlinear surface impedance (NSI); aim - development of a nonlinear integral equations method (NIE) for arbitrary shape thin wire antennas with NSI and research of nonlinear effects in such devices; methods - mathematical apparatus of electrodynamics, antennas general theory, antennas with lumped and distributed nonlinear elements theory, microwave circuit theory, and methods of the numerical analysis and mathematical modeling; results - the mathematical model of arbitrary shape thin wire antennas with NSI is developed, the algorithm and the software package based on the developed model are created, the software package is used to study nonlinear effects in is thin wire antennas with NSI (ANSI); innovation - to pioneer the availability of thin wire approximation for ANSI is demonstrated and the system of the one-dimensional NIE for thin wire ANSI is obtained, to pioneer the show strong dependence of ANSI performance on type and a level of excitation sources, as opposed to antennas with linear characteristics of a surface impedance, impossibility to use symmetric ANSI theory in a asymmetrical case is shown; level - the obtained results are used in the Kharkov state regional scientific and technical center on technical protection of the information, training process in KNURE, the software package is certificated; usage sphere - antenna farm and branch scientific research institutes engaged in development and research of antennas with nonlinear properties
