Kandrachuk I. Physical fields of receiving curved acoustic antennas with screens

The Thesis investigates and develops methods for calculating the parameters of a circular arc and cylindrical antennas for different types of screens, and analysis of processes occurring in the acoustic, mechanical and electrical fields that can be used in the design of hydroacoustic antennas. The investigations of physical fields of curvilinear antennas with screens were held. The circular and arc system was considered. As the screens locally reactive and electroelastic ones were taking into account. We consider acoustic, electric and mechanical fields. During the process of the performance we use the analytical expressions to describe all types of fields. The numerous investigations of the parameters of the fields depending on the parameters of lattices and the waves that fall were provided, their systematic analysis was made, and regularities of formation of these fields were established. The research results are confirmed experimentally. Physical interpretation of the results on which recommendations were formulated for practical implementation of such antennas was provided. The research results are applied in the production of acoustic antennas.
