Abstract
An analytical approach is taken to investigate SH wave propagation in a layered viscoelastic/piezoelectric structure loaded with nonconductive liquid. The interface between the viscoelastic layer and the piezoelectric substrate is perfect. The dispersion relations are obtained for electrically shorted and open case, respectively. The effects of the dynamic viscous coefficient of the liquid on the phase velocity and the attenuation are figured and presented.
