Nonlinear acoustoelastic interactions of lamb waves with LiNbO3 films deposited on sapphire substrates

The influence of a biasing electric field on the propagation of the lowest-order antisymmetrical a(0) Lamb wave modes in a bi-layered piezoelectric plate is investigated in this paper. It is found that the velocity shifts for the a(0) mode due to presence of the bias field on the 10-mum LiNbO3 film structure are comparable with those observed in surface acoustic waves and Lamb waves in LiNbO3 plates. The fractional change in phase velocity of the layered piezoelectric structure is a linear function of the biasing electric field and can be used in voltage sensors.
