Description

The problem of guided waves in solid/fluid/solid trilayers has been investigated in great detail both theoretically and experimentally. Lloyd and Redwood were the first to investigate guided wave propagation in a layered plate composed of two solids with perfect contact, slip, or a fluid layer at their interface [1]. Rokhlin et al. studied the elastic interface wave guided by a thin film between two solids and utilized it in predicting the strength of adhesive bonds [2,3]. Couchman et al. [4] and Guyott and Cawley [5] reported on the phenomenon of resonance splitting in the vicinity of classical Lamb modes in symmetrical trilayers. Laperre and Thys investigated elastic wave dispersion in both symmetric and asymmetric trilayers composed of two solid plates separated by a fluid layer [6]. A number of papers have appeared on the use of trilayers as antireflection coating [7–9].

Experimental Observation of the Slow Squirting Mode in Solid/Fluid/Solid Trilayers
