  The change in direction of the wavevector and group velocity experienced by a
wave refracted at the interface of an anisotropic medium in uniform linear
motion are determined analytically. These transmission conditions, which are
shown to be consistent with generalized Snell's law written in the laboratory
frame, are then used to examine the effect of motion on waves incident on a
magnetized plasma. For an incident wave in the plane perpendicular to the
magnetic field the motion is observed to lead to non negligible deviation of
the low-frequency X-mode, as well as to non-symmetrical total reflection
angles. These effects are shown to be further complicated when the magnetic
field is in the plane formed by the incident wavevector and the medium's
velocity, as the anisotropy now competes with the motion-induced drag. Although
obtained in simplified configurations, these results suggest that accounting
for motion when modeling plasma waves trajectory could be important under
certain conditions, calling for a more detailed quantification of the effect of
motion in actual diagnostics and plasma control schemes.
