Abstract:

An analysis of the in-plane acceleration sensitivity of ST-cut quartz surface wave resonators with the substrate extending beyond interior rectangular supports was performed. An analysis of the normal acceleration sensitivity of contoured AT- and SC-cut quartz crystal resonators supported along rectangular edges was performed. In subsequent work it was shown analytically that the normal acceleration sensitivity of contoured quartz resonators with rectangular supports vanishes when the centers of the mode shape and support rectangle coincide. It has further been shown that the resultant in-plane acceleration sensitivity of contoured quartz resonators with rectangular supports vanishes when the centers of the support rectangle and the mode shape coincide and the active resonator region is supported symmetrically on both sides. Since the resultant in-plane acceleration sensitivity vanishes when the centers of the support rectangle and the mode shape coincide, an analysis of the influence of a relative displacement of the center of the mode shape with respect to rectangular supports was performed.
