Invisibility!

Now just wait until its portable... assasination, spying and terrorism will be brought to a whole new level.

But of course, It can work for the good side too :D

Thank god, I thought it was another shining-projector-onto-robe type of thing.

I have a question though:

What if you are inside of the invisibility sheild, and you are trying to look out? Wouldn't the light warping thing mess up your vision?

[ExoByte]

I think its mainly used for objects at the moment. Its hard to say if they'll be able to develop it for personal use. If they do, it'll need a whole new level of security systems.

But your right, it probably would mess up vision. Light would still bounce of other objects, but it wouldnt reach your eyes if you were "wearing" it. I wonder how THAT would look!

They may come up with something for that though. Hard to say. I am unsure completely on all the details, but I plan to watch this develop from now on.

It's a set of metal rings that bend microwaves around it's centre. MICROWAVES. The only thing is would cloak you from is radar.

Still, there are military applications I can think of. You could cloak a satellite in such a metal cylinder.

Oh, the guy I saw on TV said that, if we could see microwaves, it would look like a shimmering piece of metal.

If they ever make one for personal use....oh man, I'll be the first one to buy it! Wouldn't that be great for halloween, you could be a floating hand, or head, or something.

The cloak works by steering microwave light around an object, making it appear to an observer as if it were not there at all. [/b]

"If you could see in the microwave region of the spectrum, the copper ring would not quite disappear. You'd see perhaps a shadow and some slight distortion where the copper ring ought to be."

And from an article just before:
It raises the prospect of invisibility shields that could hide objects sitting right under your nose.

This isnt just for Radar. It bends the light around an object. Thus the light will not hit the object, and will not bounce from it. Rendering the object unseen to the eye. As mentioned, there is slight distortion, Imagine it as a shimmering effect. The light bends around the object, bounces off what ever is behind it, then bends back around it into our eyes.

I though that was the good side.

...wait...

oh

oops

From the BBC News article some time ago: (source) (http://news.bbc.co.uk/2/hi/science/nature/6064620.stm)
Professor Pendry said a metamaterial cloak could be manufactured to wrap around a fighter plane or tank. But, he said: "You mustn't demand that the cloak be too thin. Despite the hype around Harry Potter, this isn't anything that flaps around in the breeze; it's more like a shed."

Your airplane is going to look like a flying 80s cellphone, apparently, if you try to cloak it. Be interesting to see what happens in the future.

There already are clothes that make people partially invisible. They were developed by Japan I think. They are basically clothes with tiny cameras on one side. There is a screen on the opposite side to the camera which is where the images taken by the camera appear. It looks quite distorted though. I'll try to find a site that explains it better.

I saw the head of the project on TV. It does not bend light. Only microwaves. I underlined the key words in the sentence here, from your quote. Prospect and could. Meaning that in the future, it could be that one could invent this for light since it is possible in the microwave range.

This technique does not work for light. From the mouth of the head of the project. One would have to implement a similar technique in the nano scale for light, to deal with the size of light waves. However, the flaw of the design is that it only work for a narrow range. So, the nano light bending one would not bend microwaves. Just like the microwave bending one does not work in the light spectrum.

All I have said here and my prior post, is from the mouth of the head of the project as he explained it on Daily Planet. He even said that it is definitively not like the invisibility cloak from Harry Potter.

Right now, this particular method can be used to shield from radars operating in the microwave range only. It is bulky and the only application worth investigating is satellite cloaking from radar detectors. Any device operating at other frequencies would detect the structure. To shield a 2 feet diameter satellite, you would need a 30 feet diameter device.

It is cool though.
