Draw schematically the effect of an applied DC or AC voltage on the TSM crystal. What conditions should be fulfilled by the AC voltage in order to affect the crystal?

What are the characteristic features of a TSM acoustic wave and what conditions should be fulfilled by the wave in order to obtain resonant vibration?
