Theoretical and experimental study of the temperature characteristics of near-surface bulk-acoustic-wave devices
Abstract
A numerical method for calculating the phase, energy, and temperature characteristics of near-surface bulk acoustic waves (NSBAW) is proposed which takes into account differences in the directions of phase and group velocities. The calculated temperature characteristics of a NSBAW device in an ST cut of quartz are found to agree well with experimental data. A number of thermally stable quartz cuts for quasi-shear near-surface waves are found which are suitable for thermally stable high-frequency NSBAW devices.
