Akhmedov. R. Field of Impulse Radiating Antennas in Linear and Nonlinear Medium – Manuscript. Dissertation for the degree of a candidate of physical and mathematical sciences in specialty 01.04.03 Radiophysics. V. N. Karazin Kharkiv National University of the Ministry of Education and Science of Ukraine, Kharkiv, 2020. The manuscript is a theoretical investigation of impulse ultrawideband electromagnetic field properties in near and far radiation zones. The whole thesis topic is united by the same approach of radiation and reception problems solving with an attention to near zone еffects. The idea of the approach is to avoid furrier transform and provide a solution in time domain. As the result the solution will not carry near radiation zone as a spatial case of radiation. Most of problems considered in the manuscript have impulse radiating antenna as a source of electromagnetic filed. The attention to near radiation zone is caused by energy concentration with nonlinear interactions and impulse shape distortion.
