By means of numerical computation, pulse mode of a piezoelectric radiator in the form of a plate, loaded with a liquid and connected to R-L circuits in various combinations, is investigated. The computations were carried out having taken into account the internal resistance of the electric generator. Numerical results, based on the theory, are provided for examples of parallel and series circuits connected to a piezoelectric plate. The optimal values of parameters are determined, providing minimal duration of radiated acoustic pulses.

The operation of a piezoelectric plate in a pulse mode is analyzed. The transmitter is excited by a main signal that is fed at the initial time moment and a compensating signal at a specified time moment. A water medium was chosen as the acoustic load. The back side of the plate borders on air. The possibility of stopping a transient process in a transducer by feeding a compensating pulse at a required moment is shown by the numerical-theoretical technique on the basis of the D’Alembert method.
