Analytical relations describing the electric fields of a radio-electronic element made in the form of a piezoceramic cylindrical shell with an internal acoustic screen and an elastic medium in the cavity between them are obtained by the method of coupled fields in multiply connected regions. A comparative analysis of the results of a numerical experiment carried out according to the frequency characteristics of the electric current of the element excitation, depending on the parameters of the design of constituents of the element, made it possible to establish a number of subtle effects in the formation of fields that are important for matching the element with the electronic generator that excites it. Possible ways to control the dynamic properties of the electric field of the transducer are determined for different compositions of the piezoceramic material of its shell and different distances between the screen and the shell. The ways of controlling the properties of the electric field of the transducer are determined, which include changes in the composition of the piezoceramic material of its shell, the dimensions of the inner screen and the distance between the screen and the shell. The results obtained make it possible to support the requirements for generator devices to ensure the energy efficiency of the corresponding radiating paths. |
