And I quote:
WASHINGTON - Harry Potter and Captain Kirk would be proud. A team of American and British researchers has made a Cloak of Invisibility.
Well, OK, itÆs not perfect. Yet.
But itÆs a start, and it did a pretty good job of hiding a copper cylinder.
In this experiment the scientists used microwaves to try and detect the cylinder. Like light and radar waves, microwaves bounce off objects making them visible and creating a shadow, though it has to be detected with instruments.
If you can hide something from microwaves, you can hide it from radar ù a possibility that will fascinate the military.
Cloaking differs from stealth technology, which doesnÆt make an aircraft invisible but reduces the cross-section available to radar, making it hard to track. Cloaking simply passes the radar or other waves around the object as if it werenÆt there, like water flowing around a smooth rock in a stream.
The new work points the way for an improved version that could hide people and objects from visible light.
Conceptually, the chance of adapting the concept to visible light is good, cloak designer David Schurig said in a telephone interview. But Schurig, a research associate in Duke UniversityÆs electrical and computer engineering department, added, ôFrom an engineering point of view it is very challenging.ö
Nonetheless, the cloaking of a cylinder from microwaves comes just five months after Schurig and colleagues published their theory that it should be possible.
Their first success is reported in a paper in FridayÆs issue of the journal Science.
ôWe did this work very quickly ... and that led to a cloak that is not optimal,ö said co-author David R. Smith, also of Duke. ôWe know how to make a much better one.ö

Awesome, that's a pretty good start to that technology...

I would like a cloaking device, but I think it'll be a looooooong time till they perfect it. Plus it'd change the face of modern warfare (again).

I wonder if that cloak works from all viewing angles? Or just from the "upstream" & "downstream" positions...
Would be kind of useless to have a cloak that only works with that limitation...

"The first working cloak was in only two dimensions and did cast a small shadow, Smith acknowledged. The next step is to go for three dimensions and to eliminate any shadow."
Who knows, nothing good will come from this technology mark my words 
The Military must be falling over themselves at the prospect.

just remember, since light is bending around the object, say your body for example, the object will not receive any of that light, effectively making that object blind.

Damn, I was just going to psot this, except the Yahoo article instead.
This is pretty neat though. Microwave now, but the future may hold light.

Considering modern armies are leaning towards lighter faster vehicles if this technology could be made to work for said vehicle, well i can see this being a perfect addition to such a light fast vehicle.
And if what was stated in the article was true not only is it close to being viable but its other aplications [such as cloaking seismic waves] could be a lifesaver.

I had another thought. If light could not be duplicated, then the cloaking could be hemispherical. That is, all light coming from behind the man / vehicle would pass thru him toward the enemy, and all light heading straight on to him from the enemy would be received by the man / vehicle, so he could see everything ahead of him, nothing behind him. The enemy would not see him approaching, but someone behind him would see him moving forward. Side angle views would depend on actual angle.

I was under the impression that seismic waves was the transfer of kinetic force on a bloody huge level. Thus, this would not help afaik.

One thing though, say you made somthing invisible to radar, won't that vehical itself be blind to radar as well (including it's own)?
Same thing with the light, great you can make yourself invisible but you can't see a ruddy thing either since all the light you'd use to see is being bent around you.
I have the body of a supermodel. I just can't remember where I left it.

Tthe only way around this is to use a periscope, something that would pick up the light outside of the voidsphere, and channel it to your eyes. The smaller the better

Thermal Imaging would still work though... you would be able to see out and if the enemy is using it you'd be S.O.L

I read about this in the paper last week (I think), it's really quite interesting, and seems to be much better than anything else currently out.
Although, being able to hide items from light/radar could be really quite scary if certain countries got a hold of it, you'd possiby be able to hide installations and buildings quite easily (thinking, missile silo's and factories and stuff), could quite effectively mask a military buildup to a degree.
And in reference to that bbc article 2 posts up...it's essentially just a projector screen in a trench coat, you still need to project the image onto it to appear invisible.
