Query: Fresnel-Fizeau drag: Invisibility conditions for all inertial observers   It was recently shown [Halimeh et al. arXiv:1510.06144 (to appear in Phys.
Rev. A)] that as a result of the Doppler effect, inherently dispersive
single-frequency ideal free-space invisibility cloaks in relative motion to an
observer can only cloak light whose frequency in the cloak frame coincides with
the operational frequency of the cloak, although an infinite number of such
rays exist for any cloak motion. In this article, we show analytically and
through ray-tracing simulations that even though this relationship can be
relaxed by simplifying the ideal invisibility cloak into a broadband amplitude
cloak, Fresnel-Fizeau drag uncloaks the phase of light in the inertial frame of
the cloak thereby compromising its amplitude cloaking in all other inertial
frames. In other words, only an invisibility device that perfectly cloaks both
the amplitude and the phase of light in its own inertial frame will also
(perfectly) cloak this light in any other inertial frame. The same conclusion
lends itself to invisible objects that are not cloaks, such as the invisible
sphere.
