In the absence of damping, there is power flow along the interface in the reststrahl regions, even at normal incidence, and this leads directly to a shift similar to the Goos-Hanchen shift normally associated with oblique incidence radiation. In the bulk regions, such a shift is still possible even without this type of power flow. In this case the beam transmitted into the antiferromagnet is displaced in the direction opposite to that of the reflected beam, thus ensuring overall flux continuity.
