Invisibility cloak 'step closer'

For now, the invisibility cloak remains a thing of science fiction

Scientists in the US say they are a step closer to developing materials that could render people invisible.

Researchers at the University of California in Berkeley have developed a material that can bend light around 3D objects making them "disappear".

The materials do not occur naturally but have been created on a nano scale, measured in billionths of a metre.

The team says the principles could one day be scaled up to make invisibility cloaks large enough to hide people.

Stealth operations

The findings, by scientists led by Xiang Zhang, were published in the journals Nature and Science.

The new system works like water flowing around a rock, the researchers said.

Because light is not absorbed or reflected by the object, a person only sees the light from behind it - rendering the object invisible.

The new material produces has "negative refractive" properties. It has a multi-layered "fishnet" structure which is transparent over a wide range of light wavelengths.

The research, funded by the US government, could one day be used in military stealth operations - with tanks made to disappear from the enemies' sight.

that is awsome technology

I want one.

Ofcourse science creates more stuff for wars. It's beyond help they get so much worshipped in education.

WOW!! I am definitely going to put that on my Christmas list!!!

THE INVISIBLE MAN
Inventor: Susumu Tachi, Masahiko Inami and Naoki Kawakami

Harry Potter isn't the only academic with an invisibility cloak. A professor at the University of Tokyo has created an optical camouflage system that makes anyone wearing a special reflective material seem to disappear. Here's how: a video camera records the real-life scenery behind the subject, transmits that image to a front-mounted projector, which then displays the scene on the reflective material. The system has obvious military applications and could also be used in airplane cockpits to make landings easier for pilots

As a general rule if you hear about any piece of technology in the mainstream news, we had it in the time of your grandparents, in classified projects.

Like this thing we're on now???

Isn't this the same thing that the British army were going to use on their tanks?

Hopefully politicians will be kitted out in them, one step closer to them disappearing

jayelowell · 11-08-2008, 03:35 PM

i would love to have one or the resources to make one

romas · 11-08-2008, 06:32 PM

Well BBC blurb is rather weak anyways, check this lecture out, they have been using semi-invisible craft for a long time, if you mask out the wings on something like B2 bomber it looks like a saucer craft

Yep the military have been experimenting with this technology for a while now and have achieved, albeit limited, success in "cloaking" armoured vehicles with it. But it is restricted in that it only "works" [sic] where the video required is accurately pre-recorded.
