Keywords: | Attenuation; Dispersion; Layered piezoelectric medium; Surface wave; Viscous liquid | Issue Date: | 2002 | Journal Volume: | 41 | Journal Issue: | 8 | Start page/Pages: | 5451-5457 | Source: | Japanese Journal of Applied Physics Part 1-Regular Papers Short Notes & Review Papers | Abstract: | In this paper, we present an analysis of the velocity dispersion and wave attenuation of a layered piezoelectric medium loaded with a viscous liquid. The eight-dimensional formalism of the surface wave and the recursive formula were adopted to obtain the impedance tensor of a piezoelectric layered half-space and that of viscous liquids. The dispersion equation of the surface waves in such a layered system was formulated under the continuity conditions at the solid-liquid interface. Numerical examples of half-space (lithium niobate), single-layered (lithium niobate/sapphire) and double-layered half-space (ST-cut quartz/lithium niobate/sapphire, lithium niobate/ST-cut quartz/sapphire) loaded with a viscous liquid are presented and discussed as well. |
