Thickness vibrations of thin piezoelectric plates and the determination of the electro-elastic constants of Al0.88Ga0.12PO4 crystal

Abstract
Thickness vibrations of thin piezoelectric plates excited by perpendicular or parallel fields have been investigated. In the analyses of the resonances of the thin plates, both the stress boundary and the electrical conditions have been considered. The theory has been applied to the determination of the electro‐elastic constants of a newly developed piezoelectric crystal, Al0.88Ga0.12PO4.
