On the resonance and antiresonance frequencies of a plate piezoceramic transducer

Resumo

Problems related to applying the concepts of resonance and antiresonance frequencies of a plate piezotransducer have been studied. The case of a plate unilaterally loaded on an aqueous medium has been researched. It has been shown that the concept of the antiresonance frequency determined with the use of an elastic modulus c₃₃^D can be applied only conditionally, still allowing one to calculate frequency characteristics for different values of a squared electromechanical-coupling coefficient. Notwithstanding the conditional nature of the term “antiresonance”, its practical use does not cause any difficulties.
