Researchers at Duke University say they've developed a way to use an off-the-shelf 3D printer to produce "invisibility cloaks" .
It involves fashioning a material with different sized holes based on an algorithm which fools microwave beams into not registering the presence of an opaque object placed at the center of the material
The design of the cloak eliminates the 'shadow' that would be cast, and suppresses the scattering from the object that would be expected. In effect, the bright, highly reflective object, like a metal cylinder, is made invisible. The microwaves are carefully guided by a thin dielectric shell and then re-radiated back into free space on the shadow side of the cloak," he was quoted as saying. .

And this is only the first one made. They're going to get even BETTER in the coming months. wheee.gif

I'll believe it when I see it. [zing] Sensationalist title.

I have an invisibility cloak on the floor in my room, but you can't see it so you'll have to take my word for it.

So...if I covered a hot dog in this...would it not cook in the microwave?

I think this would be better put towards researching other forms of waves rather than visible light. Like protection vests for X ray techs that aren't full of lead and such.

Or shielding around microwave antennas and the technicians that service them. Making something invisible to microwaves is valuable in its self.

A company last year claimed to have made a working optical invisibility cloak that they're trying to sell to the US and CA goverment. Again he doesn't release any real information on it other then he has it and respective parties of both countries have seen and can vouch for it or so he claims.

Once I read the article I realized that this does not apply to visible light. Even in their current implementation this involves a 1 inch thick structure to effect Microwave radiation.

I can see this being used for Defense...and Offense.

Hopefully they will make one in a cone shape with a chinstrap to keep de Germans from reading my thoughts. Painted chrome of course. rolleyes.gif
