Evaluation of PPS wedges, Excitation of high intensity ultrasonic waves on glass plate(Ⅱ)

摘要

We have succeeded in exciting intense SAW ona layered glass plate by using a PPS-based wedge.It was possible to move water droplets on the glassplate. The authors also proposed a gratingtransducer as an alternative method and areconducting numerical simulations for designingthe gratings. The grating transducer will be madefor trial and compare with the wedge transducer infuture.
