Abstract
The patterns of propagation of electro-acoustic waves of plane strain in a piezoelectric half-space is examined. In paper is shows how many possible variants of the boundary value problem of electro-elasticity can be formulated in a piezoelectric half-space of piezoelectric crystal class 6m2 of the hexagonal symmetry. The problem of propagation of high frequency acoustic waves of plane strain (electro-acoustic Rayleigh waves) at different electric boundary conditions for mechanically free surface of a piezoelectric half-space is discussed. The possibility of a new localization of wave’s plane strain, under certain electrical conditions at a surface is shown. The presence of a concomitant fluctuations of electric field, the waves of plane strain giving to the results in both quantitative and qualitative changes of the characteristics of a localization of electro-acoustic Rayleigh waves.
