Ultrasonic Surface Wave Transduction Techniques.
Abstract
The work conducted on Project E1059 has been an extension of that begun on Projects E1014, E1022 and continued under Project E6044. Primarily, this work has been concerned with the development of techniques for tapping ultrasonic delay lines. These techniques utilize thin deposited conducting, piezoelectric, and piezoresistive films on a Pyrex glass substrate. The mode of propagation has been the surface wave which provides maximum energy on the surface and is free from dispersion and reflections. Details of the techniques developed may be found in IITRI Technical Note No. 02-3, entitled 'Thin Film Multi-Tap Delay Line' authored by R. J. Serafin and A. P. van den Heuvel. Effort on this program has concerned itself with investigation of piezoelectric taps employing a vertical geometry. A thin film surface wave generator was designed and successfully deposited. During the program a paper entitled 'Measurement of Strain and Velocity of Ultrasonic Surface Waves' was submitted and accepted for publication in the October 1967 issue of The Review of Scientific Instruments.
