Abstract :
Boundary conditions for a layered piezoelectric structure under the influence of a uniform dc electric field have been obtained. Dispersive dependences and anisotropy of phase velocities, electromechanical coupling coefficients, power flow angle, and controlling coefficients of dc electric field influence as a functions of h×f product for the Rayleigh and Love modes in bismuth germanium oxide/fused silica and langasite/fused silica layered structures have been calculated.
