Investigation of SAW and PSAW propagation in LGS crystal by scanning electron microscopy method

摘要

This paper reports the investigation of the SAW and PSAW propagations in X-, Y- and Z-cuts of LGS crystal by scanning electron microscopy method which is very useful for qualitative and quantitative analysis of acoustic radiation wavefields in piezoelectric materials. Using the scanning electron microscopy method we visualized the diffraction patterns in the acoustic beams on the crystal surface and determined the power flow angles for SAW and PSAW.
