Abstract
Diffraction of the plane shift electroelastic wave on the semi-infinite metal layer in piezoelectric space with infinite metal layer is discussed. Solution of the problem can be brought to the solution of Riemann problem in analytic functions theory, using real Fourier transformation. Asymptotic formulae of shift amplitude in further zone are found. It is shown that the existence of semi-infinite metal layer leads to appearance of surface and cylindrical waves and a wave which propagates in the direction of the beam, with a speed depending on the angle of beam spread.
