The swept frequency acoustic resonant interferometer: measurement of acoustic dispersion parameters in the low megahertz frequency range

Abstract

The general principles of operation of the swept frequency acoustic resonant interferometer are outlined and its use for measurements of energy loss and velocity dispersion in the low megahertz frequency range discussed. A number of different variations on the design of the resonator are described. Data on a variety of chemically different systems are presented illustrating the range and versatility of the technique for measurement of samples with low acoustic losses.
