On the problem of the frequency dependences of the input electric impedance of a broadband immersion transducer
Source abstract
Abstract
A piezoelectric plate with a damper and a matching layer is considered. Water was chosen as an acoustic load. On the basis of the use of the apparatus of circuits-analogues of piezoelectric transducers (PETs), the relationships were obtained that determine the frequency dependences of the modulus and phase of the input electric impedance of the considered transmitter. Numerical investigations of the aforementioned electric characteristics of the PET were performed within a wide band of relative frequencies and the interrelationships of these characteristics with the shape of the frequency characteristics of the PET-transmitted acoustic power were studied.
