Pseudo-Rayleigh wave

Fig. 11.4. Velocities of bulk and surface waves in an (001) plane the angle of propagation in the plane is relative to a [100] direction, (a) Zirconia, anisotropy factor Aan = 0.36 (b) gallium arsenide, anisotropy factor Aan = 1.83 material constants taken from Table 11.3. Bulk polarizations L, longitudinal SV, shear vertical, polarized normal to the (001) plane SH, shear horizontal, polarized in the (001) plane. Surface modes R, Rayleigh, slower than any bulk wave in that propagation direction PS, pseudo-surface wave, faster than one polarization of bulk shear wave propagating in...

Fig. 11.8. Rayleigh and pseudo-surface wave velocities measured on GaAs(OOl), indicated by +. The solid lines are the calculated curves of Fig. 11.4(b) (without the longitudinal wave curve), plotted on the enlarged vertical scale used for the experimental...
