The development of micro-acoustic wave sensor in biosensing created the need for further investigations of the surface wave propagation in a viscous liquid loaded layered medium. In this paper, we employed the sextic formalism of surface waves to study the viscous effect on the dispersion and attenuation characteristics of surface waves in a viscous liquid loaded layered medium. The dispersion relation for the viscous liquid loaded single-layered anisotropic half-space is given. Numerical examples of the Rayleigh wave and Love wave dispersion for the cases of a Cu/Fe layered half-space (isotropic) and of a SiO2/Si layered half-space (anisotropic) loaded with viscous liquid are calculated and discussed.

Abstract In this paper the surface wave terms of the Green's function for a two-dimensional multilayered half space are obtained. The method used is new and remarkable by its simplicity. It is based on the integral representation theorems for elastodynamics. The orthogonality properties of surface waves are generalized to include not only Love waves but Rayleigh waves as well.

Elastic wave propagation in plane strain in a periodically layered half space is considered, with the layering parallel to the bounding traction-free plane. Attention is focused on surface waves of the Rayleigh-type propagating parallel to the bounding plane. It is found that such waves are highly dispersive and that higher branches may be discontinuous.
