摘要
The paper proposes a technique to derive the dispersion relations for acoustoelastic shear body waves propagating in periodically layered media formed of identical metallized sandwiches, each consisting of two different piezoelectric layers and a dielectric layer between them. A numerical analysis is carried out and the propagation of body waves in different structures is described for a wide range of frequencies and wave numbers. The effect of the physical, mechanical, and geometrical parameters of the layers on the transmission and suppression bands is examined. The influence of the piezoeffect on the arrangement of the transmission edges upon change in the relative thickness of the layers is studied
