Huijing He, Jinxi Liu and Jiashi Yang. "Analysis of a monolithic crystal plate acoustic wave filter" Ultrasonics Vol. 51 (2011) p. 991 - 996


We study thickness–shear and thickness–twist vibrations of a finite, monolithic, AT-cut quartz plate crystal filter with two pairs of electrodes. The equations of anisotropic elasticity are used with the omission of the small elastic constant c56 . An analytical solution is obtained using Fourier series from which the res-onant frequencies, mode shapes, and the vibration confinement due to the electrode inertia are calculated and examined.
