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