Abstract
The presence of a liquid layer on the Rayleigh wave delay line is found to increase the original delay by a factor of 2 with loss of only a few percent in amplitude. Different modes with variable delay can be excited simultaneously and can be picked up by another transducer in contact with liquid layer. Possible uses of thin layer waves as an acoustic interferometer are discussed.Keywords
