Аннотация: Basic equations and boundary conditions describing the propagation of acoustic waves in piezoelectric layered structures subjected to uniform pressure have been obtained. The propagation of dispersive acoustic modes in the [100](001)BGO/fused silica and fused silica/[010](100) LiNbO3 layered structures has been analyzed in detail. Показать полностьюSelection of solutions identified as the Rayleigh and Love modes of various orders has been fulfilled. Dispersion relations for the phase velocity, EMCC and coefficients ?v in terms of parameter h?f have been obtained. Anisotropy of acoustic wave parameters in the (001) BGO/fused silica structure has been investigated. Directions with the maximum values of the coefficients ?v have been found for some acoustic modes. © Siberian Federal University. All rights reserved.
