On fitting parameters of multilayer resonant ultrasonic chamber

The paper describes a multilayer ultrasonic chamber with losses. Relations for calculating the chamber resonant frequencies by various methods have been derived. Therefore, it became possible to tune the chamber to resonance by varying the chamber layer geometry and acoustic characteristics. Relations for calculating radiation pressure in the chamber layers for the cases of zero and non-zero coefficients of the chamber wave "mobility" are presented. Numerical examples are analyzed.
