Acoustic waves in thin plates of lithium niobate

By the example of lithium niobate, the main features of the propagation of antisymmetric (A(0)) and symmetric (S-0) Lamb waves and the waves with transverse horizontal polarization (SH0) in thin piezoelectric plates are theoretically analyzed. The obtained results may be used in the development of signal processing devices, various types of sensors, and chemical and biological instruments on the basis of acoustic waves propagating in lithium niobate plates.
