A question about ultrasonic wave

[fannyfanfanz]

Hi,

When a linearly polarized shear wave enters an anisotropic material, shear wave splitting (a fast and a slow shear waves) will occur.
My question is, under normal incident, will the fast shear wave speed vary if the polarization of the incoming shear wave changes?

Thanks!

Not sure how you can have wave splitting at normal incidence, so rotating polarization will not have any effect.

If the propagation direction of the shear wave is not parallel to the c-axis (assuming the material is transversely isotropic), the shear wave will split at normal incidence.
