Surface waves in coated anisotropic medium loaded with viscous liquid

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.
