THICKNESS VIBRATIONS OF THIN PIEZOELECTRIC PLATES AND THE DETERMINATION OF THE ELECTROELASTIC CONSTANTS OF AL0.88GA0.12PO4 CRYSTAL

Thickness vibrations of thin piezoelectric plates excited by perpendic ular or parallel fields have been investigated. In the analyses of the resonances of the thin plates, both the stress boundary and the elect rical conditions have been considered. The theory has been applied to the determination of the electro-elastic constants of a newly develope d piezoelectric crystal, Al0.88Ga0.12PO4. (C) 1996 American Institute of Physics.
