Annotation
In the paper influence of various electric boundary conditions on distribution of components of mechanical displacement and electric field on plate thickness is investigated. As a result of the carried out researches the possibility of control by the penetration depth and the place of a maximum of shift of the backward waves in XY potassium niobate by use of various types of an electric shortening of a plate has been found. The obtained results can be useful to development of methods of control of shift of particles of the piezoelectric environment at propagation of backward acoustic waves.
