Although these guys are from a real place, it's still a theory paper... Wait until one comes out from engineers. Also, according to them, it only works for single frequency, and would only work for many frequencies (say, normal light) if immersed in a medium with high index of refraction. Most materials with high index of refraction would make it invisible anyway =)
