From The Economist print edition http://www.economist.com/science/displaystory.cfm?story_id=6971134 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.
