Theoretical analysis of damping effects of SAW at solid/fluid interfaces

A theoretical of ideal and viscous fluid media is proposed to address the problem of modelling damping effects of surface acoustic waves (SAW) at the interface between fluids and solids. It is based on the Fahmy-Adler eigenvalue representation of the elastic propagation problem, extended to provide the Green's function of the considered media. It takes advantage of previous efforts developed to numerically stabilize the Green's function computation process. The influence of acoustic radiation and viscosity on different kind of surface waves on various substrate is reported and discussed.
