Abstract
An approach to calculating resonance frequencies and acoustic characteristics of ultrasonic multilayer liquid chambers bordering an air or liquid half-space and loaded to a piezoelectric emitter is proposed. The assumption on the validity of plane motion is accepted. The approach allows for obtaining comprehensive data on physical processes in the chamber. The equation relating electrical admittance of a piezoplate with input impedance of the acoustic load is derived. An unloaded emitter and an emitter loaded to acoustic resistance with constant and frequency-dependent impedances are considered as examples.
