Abstract
The characteristics of antisymmetric and symmetric Lamb waves, as well as quasi-shear-horizontal waves, propagating in thin potassium niobate plates are investigated theoretically. It is found that the square of the electromechanical coupling coefficient of acoustic waves in such plates can reach 100% in certain directions. The results obtained indicate that potassium niobate is a highly promising material for creating various acoustoelectronic devices.
