These cloaks typically work by converting an incoming photon into a surface plasmon, a wave of electron oscillations. By carefully tweaking the surface geometry it is possible to get the wave to interfere with itself so that the photon is re-emitted at the opposite side of the cloak, at least if the cloak shape is symmetric enough. http://en.wikipedia.org/wiki/Surface_plasmon |
