摘要:
Results are presented for the propagation of circumferential acoustic waves around a thin-walled stainless steel tube. Sol gel lead titanate-zirconate (PZT) films and chirp interdigital transducer (IDT) electrodes were used to generate theA0mode from 0.8 to 6.0 MHz. Group and phase velocity measurements are in good agreement with the theory for the empty tube. When the tube is filled with water a large decrease of 21% in group velocity is observed. While there is as yet no theoretical explanation for this effect, the results show promise for liquid sensing applications.
