Calculation of resonance frequencies of an ultrasonic multi-layer chamber with a piezoelectric radiator

The paper suggests an approach to calculation of characteristics of an ultrasonic resonance chamber consisting of a piezoelectric radiator and multi-layer liquid chamber adjacent, generally, to the liquid half-space. The method suggested allows one to get exhaustive information on intra-chamber physical processes. For instance, a non-loaded radiator and a radiator loaded with acoustic resistances with both constant and frequency-dependent impedances have been considered.
