Scientists claim invisibility breakthrough

It is the closest scientists have come yet to recreating Harry Potter's invisibility cloak.

An ultra-thin flexible material has been developed that can wrap around an object and make it vanish.

Although the "invisibility skin" has only been tested at microscopic scales, scientists believe it should be possible to create larger versions in the future.


Harry Potter wears his invisible cloak in a screengrab from the popular movie series.

The 80 nanometre thick film is made from gold "nanoantenna" blocks that interfere with the normal scattering of light waves.

In the test, the "cloak" was wrapped around a tiny lumpy and dented "bump" measuring 36 micrometres square - about the size of a few living cells. Once activated by switching the polarisation of the nanoantennae, it made the object invisible.

Lead researcher Dr Xiang Zhang, from the US Department of Energy's Lawrence Berkeley National Laboratory, said: "This is the first time a 3D object of arbitrary shape has been cloaked from visible light.

"Our ultra-thin cloak now looks like a coat. It is easy to design and implement, and is potentially scalable for hiding macroscopic objects."

In the Harry Potter stories, the boy wizard hides from his enemies using a cloak that renders the wearer invisible. It works by magic rather than the light-channelling "metamaterials" used by scientists.

Metamaterials have features smaller in size than the wavelength of light, allowing them to re-route incoming light waves.

Previous invisibility experiments have produced bulky, rigid designs that cannot be adapted to different environments.

The technology, described in the journal Science, holds promise for applications such as high resolution microscopes, super-fast optical computers, and 3D displays.

However it is still a long way from providing the perfect camouflage for soldiers and military vehicles, or allowing spies to creep around unseen.

Any movement by the object being hidden currently breaks the invisibility "spell". Also, the "cloak" only works over a limited range of light wavelengths.

Hmmm brilliant science I wonder what applications we have for this. More fakes????

October 19, 2012, Vancouver, B.C.) Once thought to be only a Science Fiction/Fantasy technology, Guy Cramer, President/CEO of Hyperstealth Biotechnology Corp., discusses the implications of militaries which can now become invisible with his light bending technology called "Quantum Stealth".

Hyperstealth is a successful Canadian camouflage design company with over two million military issued uniforms and over 3000 vehicles and fighter jets using their patterns around the world.

Quantum Stealth is a material that renders the target completely invisible by bending light waves around the target. The material removes not only your visual, infrared (night vision) and thermal signatures but also the target’s shadow.

stunning technology makes troops invisible 9 minute video. really cool video.

In my mind the tech is already here!

2 thoughts relating to the operative who climbs into the tank:

1) He looks like he is in a non-standard all over suite, not carrying any objects and or weapons. Because any objects and or weapons would have to be cloaked in the same material! Unless the tech being used was a energy field of some kind, which wasn't the case here!

2) Ok the operative was virtually invisible while running to the tank but! why did he suddenly become visible when reaching the tank? Is it a switchable material/tech, if so why not Waite till in the tank?

opening post, very interesting as-well

This idea has been gaining ground over the past decade... N

from 2009, Japanese Scientists make invisibility cloak..

This last ones interesting, not sure if its real or fake, very interesting..

My favorite invisible plane photograph:




(...this is a spoof, of course.)

But, not a spoof: Camelot witness Henry Deacon (Arthur Neumann) told us that he had been in one military establishment where all along one corridor there were high-definition posters of advanced, or classified, aircraft, all chronologically through the ages as one walked down the corridor. You can imagine: the U-2, the SR-71, the F-117A, the B-2.... and so on.

The last poster showed nothing but blue sky and clouds. The aircraft, whatever it was, was invisible.

[Henry Deacon]

That was years ago... The invisible(stealth) aircraft was a new type of Navy Bomber (McDonald Douglas) It was similar in size to an A7. It was in the R&D/testing mode at that time... The photo mentioned, was in an office on an Island Naval Base in the state of Washington.

That aircraft was on a flight-line, along with other aircraft and their associated ECM R&D/test projects.

There were no classified marking on that photo.
Maybe because the Photo only showed sky and a few clouds, etc.

It did/does not use lighting effects, such as those placed on the leading edges of wings, etc. It can fully cloak a wide spectrum (EM from DC up through light and beyond). There is a way to detect that aircraft and other (now public) airborne platforms which create certain types of 'disturbances' above the Earth's surface.... How the detection is accomplished is quite interesting but, please lets leave that alone.

What has been observed here in Oregon could be another example of cloaking.

Personally don't endorse thirdphaseofmoon and when they came to me and asked if they could use the Oregon footage that was filmed I said no. So what they made was a CGI rendition but was is important is the testimony from the young child. The boy personally viewed the object closer to the ground and seen shape of a triangle long and narrow...

I included some footage and Bills newsletter article to elaborate more...

is this not trivial to achieve (highlighted in red above)? black body (mag-trap) would do the job and this is how you make it in your kitchen?
