Abstract
A surface wave device, including: a quartz substrate; a piezoelectric thin film formed on said quartz substrate; and comb teeth electrodes formed in contact with the piezoelectric thin film; said piezoelectric thin film of such a thickness being controlled to be able to oscillate a higher-order mode of leakage elastic surface waves.
Bench mark system using elastic surface waves - comprises substrate on which waves are propagated in perpendicular directions to be picked up by transducer probe
