Abstract
We present first measurements on acoustic waves with quasi longitudinal polarization on quartz and lithium tantalate substrates as well as layered systems carried out by a scanning acoustic force microscope (SAFM). Acoustic phase velocities were measured for microscopic areas showing a good agreement with numerical calculations. The influence of the penetration depth of the high velocity pseudo SAWs (HVPSAW) on the SAFM signal formation is discussed.
