6. This surprising occurrence of asymmetric wave polarization related with unmistakably symmetric LSAW wave velocity is associated with the very small leakage of the LSAW into shear bulk-acoustic waves. The Rayleigh waves on this same cut exhibit symmetry about the X-axis for both velocity and polarization.
