摘要
Techniques are provided for determining certain correction factors and using these correction factors in analyzing the vibration frequency characteristics of a piezoelectric material. The correction factors are developed based on the Mindlin plate theory and are introduced to correct the inaccuracies of higher-order thickness-shear cut-off frequencies. The analysis is preferably carried out during the design of a piezoelectric device incorporating the piezoelectric material and before production of the piezoelectric device. The design state may also include determining whether the device and its electrodes exhibit appropriate stiffness characteristics.
