Abstract: The effect of uniaxial mechanical pressure on the dispersion characteristics of Lamb waves and SH-waves in multilayer piezoelectric structures is studied for different variants of uniaxial mechanical pressure application. The conditions of uniaxial mechanical pressure application are noted, under which changes in the phase velocities of Lamb waves and SH-waves are maximal or absent, which can be of great importance for the development of controlled acoustoelectronic devices.

Keywords: multilayer structures, aluminum nitride, hybridization, backward acoustic waves.
