摘要：

We introduce a new method for observing the anisotropic propagation of surface acoustic waves on solids. Point source and point detection of ultrasonic waves, scanned as a function of propagation angle, give the group velocities and intensities of Rayleigh and pseudosurface waves. Group-velocity focusing and internal diffraction are observed for Si, and a new Rayleigh mode, induced by water loading of the surface, is discovered. Such effects are predicted for most anisotropic solids. © 1995 The American Physical Society.
