Abstract
The reflection, amplification and absorption of plane electro-elastic shear wave from the boundary of piezoelectric rhombic crystal of 222 class and semiconductor in the absence of acoustic contact is considered. The wave fields' in the piezoelectric crystal and semiconductor are found. The amplitude ratios of arising waves are determined. It is shown, that in the crystal the attendant surface waves are occurred, in consequence of which, the amplification is took place.
