Abstract
A thin-film resonance technique is described for measuring the dispersion and absorption of acoustic waves in lossy liquids from 0.5 to 2.2 GHz. The method uses Bragg scattering of laser light to measure the incident and reflected acoustic power from a 4.2- liquid film formed between two sapphire rods. It is shown how the velocity and absorption are calculated from the measured acoustic reflection coefficient. The technique is used to study the two resins.
