A plane electromagnetic wave incident on the interface of a dielectric medium made of a piezoactive material leads to the excitation of elastic shear waves. Piezoelectric material is assumed to have 6mm class hexagonal symmetry. The case of a half-space and a finite layer is considered. Coefficients of reflection and refraction are determined. In the problem of an electromagnetic wave incidence on a half-space made of a piezoelectric material of hexagonal symmetry, class 6 mm, the nature of the piezoelectric effect influence on the transparency condition is established. In the case of reflection from a finite piezolayer, reflection coefficients are determined for different variants of boundary conditions.
