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.
