Thermal Hysteresis In Acoustic Resonators, Lee W. Casperson, Lloyd M. Davis, John D. Harvey

Electrical and Computer Engineering Faculty Publications and Presentations

In some applications of piezoelectrically driven acoustic resonators, the power dissipated in the resonating material may be sufficient to significantly change the temperature and hence the resonance frequency. A straightforward analysis shows that this effect can lead to severe hysteresis and thermal bistability. This model is in agreement with experiments that have been performed using a fused silica acousto‐optic modulator.
