Mathematicians Design Invisible Tunnel

New calculations show how to make an electromagnetic "wormhole" — a tube that is invisible from the sides but allows light to shine down the center. The practical applications are a ways off, as even the design of a spherical invisibility cloak has not advanced beyond working (in theory) for a single wavelength of visible light.

this is a good application for the army. a series of tunnels and your moving trucks and cargo without the enemy seeing them. all they would know is that you have the tunnels but would'nt know exactly what your moving.

Designed?!?

I don't quite see how anyone can claim they designed such a thing. It is sort of like saying Klein designed a bottle that holds everything on the outside on the inside. Of course a Klein Bottle is impossible to construct, sure it's an interesting mathematical idea but it's not anything you can make in reality, so it's senseless to say it's been designed. Let's just say it's been imagined.

The one application that struck me is the holographic implications. If you can get light to move to a precise spot in mid-air through an invisible tunnel, you can make objects appear anywhere. No smoke or mirrors required.

Yet, if I step into the middle of th beam, you'll see me. Not so with this tunnel.
