Surface acoustic wave devices [PDF]
SPIE Proceedings, 2007 Starting with an introduction to surface acoustic waves, their generation and detection using interdigital transducers (IDTs) on piezoelectric materials (e.g. LiNbO 3 and ZnO) will be reviewed. Then the application of surface acoustic waves in electronic devices will be presented.

A HISTORY OF SURFACE ACOUSTIC WAVE DEVICES
International Journal of High Speed Electronics and Systems, 2000This paper gives a historical account of the development of Rayleigh-wave, or surface-acoustic-wave (SAW), devices for applications in electronics. The subject was spurred on initially by the requirements of pulse compression radar, and became a practical reality with the planar interdigital transducer, dating from 1965.
