Distribution of acoustic fields of backward acoustic waves along the thickness of piezoelectric plate

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.
