Surface Waves and Anomalous Sound Absorption.

Abstract

A theoretical model of surface waves in equilibrium with acoustic waves at a fluid-fluid interface is developed. Modifications to the usual pressure and particle velocity boundary conditions lead to a dispersion relation for the waves of the coupled system. An expression for the total reflection coefficient is found. The ratio of acoustic energy absorbed due to reflection from the interface to the incident wave energy is calculated making use of the previously obtained reflection coefficient. (Author)
