Abstract
We derive an analytic expression for the Goos–Hänchen shift experienced by an acoustic wave that is totally reflected at the interface between a negative-refractive-index acoustic medium and a positive-index acoustic medium. Upon obtaining the condition necessary for phonon-trapping in a three-layer heterostructure, we introduce a design for an "acoustic clepsydra" by using a suitable acoustic heterostructure.
