title: General properties of the acoustic plate modes at different temperatures.
abstract: Using acoustic plate modes with SH-polarization and quartz crystal with Euler angles 0°, 132.75°, 90°, as an example, general properties of the acoustic plate modes at different temperatures are studied theoretically and experimentally in the range from -40 to +80°C. It is shown that in addition to well-known parameters responsible for temperature characteristics of acoustic waves the temperature coefficients of the acoustic plate modes depend on the mode order n, plate thickness h/λ, and expansion of the plate in direction of its thickness (h - thickness, λ - acoustic wavelength). These properties permit the mode sensitivity to be increased or decreased without replacing plate material and orientation.
