One Step Closer to Cloaking Devices

We're one step closer to cloaking Devices, now they can be scientifically theorized; but they're not sapping your sentry just yet.

One of the main failings of games and science fiction in general is that whilst some inventions (like teleportation, androids, and so forth) are really cool, they fail to deal with real physical laws and are sniffed at by 'proper' scientists. Now, however, scientists have found a theory to produce invisibility whilst still remaining within physical laws.

The original research here [http://eetimessupplynetwork.com/researchnews/212200640], is very heavy on the physics, so I'll do my best to translate.

Two years ago, an Anglo-US team managed to create a 'cloak' which could hide an object from microwaves. As microwaves are part of the bumping around in bandages. [http://en.wikipedia.org/wiki/Electromagnetic_spectrum]

The cloak was made out of a Metamaterial [http://en.wikipedia.org/wiki/Metamaterial], of copper wires fastened around fiberglass. As the microwaves struck the cloak, they flowed through the copper without affecting the surface.

Earlier this year, scientists in California built a cloak that could negatively refract visible light, in the same way that water does. They were nearly there, but it took a team from Scotland and the Czech Republic to finally nail the starting point.

The breakthrough came when they started using Non-Euclidian geometry [http://en.wikipedia.org/wiki/Non-Euclidian_geometry] to describe how such a cloak would work.

In essence, the new cloak would present a surface similar to a sphere, where the light coming towards the object would be streamlined around it, in the same way that an aircraft diverts air around its wings. The beauty of this theory is that it will divert light from all sides, whilst leaving the person underneath the cloak able to see.

So Team Fortress's Spy doesn't yet exist, but the theory to create him does.

Watch this space. And if you don't see anything, you know it's worked.

I heard something about this, or at least something like this.

The idea was the material was covered in nanotubes that refracted the light around the object or something. Not a physicist here so I have no bloody idea, I just know it's pretty damn cool.

This is pretty cool. I had no idea that science had progressed enough to do even this much.

Didn't they idea come from cats' eyes? The way the reflect (refract) light makes them shine it back completely at an observer suddenly from certain degrees, and some science-y guy saw this and was all like "Of course! Non-Euclidean geometry!" That's the whispers I heard about this anyway.

great, now I need a flame-thrower everywhere I go.
And now they'll have to do spy checks at the airport as well, like it doesn't take long enough to get through everything there.

I remember reading about this. One of the biggest potential flaws is that Metamaterial is simply too big and unwieldly to fashion into a cloak - the material itself is better used to hide stationary objects. Still, mass producing the stuff would allow them to improve its quality, and the neccesary quantities with it. Then again, if they ever do mass produce this stuff, I predict it'll be the end of the world.
Invisible tanks, anyone? :p

Hehe next thing you know the upper-class-paranoid-around-town will be using this knowledge to upgrade their tin foil hats.

theres an article in popular science. were the japanese wear a coat and they have a projector and it plays...well nevermind i guess thats different from this one.
