How to weave a cloak that makes you invisible
The invisibility claim does not follow from the theory. The
electromagnetic,
waves, even if they maintain the exact same path and polarization
after the
object, will be delayed by "going around". Since the speed of light
cannot
increase beyond c, there is no way to make up for the delay. The
object can
be seen by a simple interferometer arrangement.
