Metamaterial Coating Hides Objects From Detection

Provided by A'ndrea Elyse Messer, Penn State Developing the cloak of invisibility would be wonderful, but sometimes simply making an object appear to be something else will do the trick, according to Penn State electrical engineers....

Chuck Bednar for redOrbit.com – Your Universe Online Researchers from the University of Rochester in New York have developed an inexpensive new way to create a Harry Potter-esque invisibility cloak using ordinary lenses to obscure objects from sight at a variety of angles. According to Carrie Putnam of Reuters, the device known as the Rochester Cloak is not actually a cloak at all, but a device that resembles the equipment typically used by an eye doctor. When an item is placed behind...

Lynn Yarris, Berkeley Lab There’s a new wave of sound on the horizon carrying with it a broad scope of tantalizing potential applications, including advanced ultrasonic imaging and therapy, and acoustic cloaking, levitation and particle manipulation. Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a technique for generating acoustic bottles in open air that can bend the paths of sound waves along prescribed...

Breakthrough In Creating Invisibility Cloaks
2014-04-01 11:09:29

University of Central Florida Controlling and bending light around an object so it appears invisible to the naked eye is the theory behind fictional invisibility cloaks. It may seem easy in Hollywood movies, but is hard to create in real life because no material in nature has the properties necessary to bend light in such a way. Scientists have managed to create artificial nanostructures that can do the job, called metamaterials. But the challenge has been making enough of the material...

A 3D Acoustic Cloak That Hides Objects From Sound
2014-03-12 12:14:17

Lee Rannals for redOrbit.com - Your Universe Online Engineers at Duke University have demonstrated the world’s first three-dimensional acoustic cloaking device. The scientists reported in the journal Nature Materials that they have created a new device that reroutes sound waves to create the impression that the cloak and whatever it covers is not there. This technology could one day be used by the US Navy as a way to avoid sonar detection. According to the researchers, the acoustic...
