News Stories relating to "invisible"

Invisibility cloaking is no longer the stuff of science fiction: two researchers in The Edward S. Rogers Sr. Department of Electrical & Computer Engineering have demonstrated an effective invisibility cloak that is thin, scalable and adaptive to different types and sizes of objects.
Professor George Eleftheriades and PhD student...

Up until now, the invisibility cloaks have been bulky contraptions--not easy to slip on and off for people who want to role play Harry Potter. However, researchers have now developed a cloak that is just micrometers thick.
Objects are detected when waves--whether they are sound, light, x-rays or microwaves-- rebound off its surface...

Great strides are being made, when it comes to creating invisibility.
Baile Zhang, a scientist from Nanyang Technological University in Singapore, caused his audience to gasp when he demonstrated the following experiment: He used a small box made of calcite optical crystal to bend light around an object, making anything placed behind...

How can we protect our soldiers
? Make them invisible! The US military is developing "Quantum Stealth" camouflage uniforms that can make soldiers completely invisible by bending light waves around them. This fabric can even fool night vision goggles.

WE may not yet be able
to become invisible, but scientists have succeeded in "cloaking" an object perfectly for the first time, making it invisible to microwaves. Many "invisibility cloak" efforts have been made, but they've all reflected some light, making the...

Scientists are working hard to achieve invisibility
. A group of researchers have created a cylinder which makes its contents invisible to magnetic fields.
If there's a military use for this, nobody's thought of it yet, but there are definitely medical...

A team of physicists has created a "hole in time," where things that happen are completely undetectable to ordinary observers. It's as if they never occurred. Called "temporal cloaking," this could eventually provide a way for a country like Iran or North Korea to make nuclear weapons in complete secrecy.

The brave soldiers who went in to take out Osama bin-Laden
must have wished they could be invisible. Scientists are determined to figure out how to do this. If we succeed, it would certainly be an effective tool to use in a...

We have the scan and the pat down
to thank for this: Science similar to the type used in airport body scanners could soon be used to detect everything from miniscule defects in aerospace vehicles and concrete bridges to skin cancer. There is more going on than can be...

Scientists have been experimenting with invisibility
for a long time, mostly on the quantum level. But now they've learned how to make large objects, which are visible to the naked eye, invisible as well. How do they do it?

Scientists are still trying to create an invisibility cloak. Researchers have found ways to use magnetic resonance to capture rays of visible light and route them around objects, rendering those objects invisible to the human eye.
Electrical engineer Elena Semouchkina is developing a nonmetallic cloak that uses identical glass resonators...

European researchers are perfecting the invisibility cloak that the Japanese invented. It may take a long time, but some day we may stumble over things that we don't see because, to us, they're just NOT THERE.
German scientists were able to do this by covering a tiny bump in a layer of gold, which prevented it from being detected by...

Scientists are still working on creating invisibility and have now found a way to make objects invisible in near-infrared light. Soon they may be able to create invisibility in full-spectrum light (the kind we see).Mechanical engineer Xiang Zhang has created what he calls a "carpet cloak" made up of mesh fabric. He makes some parts of the...

Scientists and the military are seriously studying how to make things like soldiers and airplanes invisible, but right now the only thing researchers can render invisible is a person (if he's wearing the right clothes). This would be great gear for a spy. But it turns out the Chinese have already figured out how to overcome this effect!

Five years ago, we reported on clothes that were being designed to make the wearer invisible. Researchers have developed a material that can bend light around 3D objects, making them seem to "disappear"?like magic! It all has to do with perception.
BBC News quotes researcher Ortwin Hess as saying, "In order to have the 'Harry Potter'...

The mathematicians who first created the invisibility cloak now think that the same technology could be used to create 3D TV.
The secret is a mathematical construct known as "wormholes." Mathematician Allan Greenleaf says, "You could pass an object into one end [of their wormhole tube], watch it disappear as it traveled the length of...

Several clothing manufacturers have experimented with acloak ofinvisibility you can wear around, but now researchers thinkthey can use this technology for something much moreimportant: making warplanes and spacecraft invisible. Thetrick: Light scattering. We can see objects becauselight bounces off them, but if this scattering of lightcould be...

Susumu Tachi, who invented a cloak that makes its wearer "invisible," now plans to develop technology that will allow people to see through walls. He says, "My short term goal would be?to make a room that has no outside windows appear to have a view to the outside, then the wall would appear to be invisible."
The cloak works by...

A Tokyo professor may have been inspired by rumored U.S. invisibility camouflage for fighter jets, which makes the lower surfaces of an airplane project an image of the sky above it, rendering the plane invisible. He's applied this technique to a coat which, when worn, makes your body seem to disappear. However, the parts not covered by the coat...
