If you want to fly under the radar, you could do with a sheet of this material. Using a series of liquid-metal absorbers, the new film can soak up radar in order to cloak whatever it happens to be covering.
Invisibility is perhaps the most ubiquitous of sci-fi dreams: Spy movies, video games, and classic cartoons all tantalize us with this trick. Researchers at the University of Rochester still haven't unlocked the secret to that elusive invisibility cloak either, I'm afraid. But they made a very cool optical illusion…
A cloaking device that makes you appear completely invisible is still trapped in the realm of science fiction. But researchers at Duke University have successfully created a cloaking device that works with sound instead, making an object completely invisible to SONAR and other acoustic imaging techniques.
The last time Keio University was in the news it was for a prototype wearable cloaking device developed by a team of researchers at the school. A decade later you still can't go out and buy one, but the research has inspired another brilliant use for the technology—invisible car interiors that let you see everything…
Mercedes claims that its new fuel cell technology results in vehicles with no emissions, so it's as if they're invisible to the environment. And to drive this fact home, literally, they created a vehicle that was invisible to everything else.
Hiding behind a life-sized negative of yourself won't actually turn you invisible. But researchers at the University of Texas at Austin have figured out how to use that same idea to make real-world objects vanish when shot with microwave energy.
Soldiers could one day conduct covert operations in complete secrecy, now that Pentagon-backed physicists have figured out how to mask entire events by distorting light.
Scientists at the Britannia Royal Navy College are working hard to make the idea of an invisible ship a reality using metamaterials that refract light in such a way that it "bends" around an object, making it appear as if it were invisible. This would only account for viewing with the naked eye however—naturally radar…
DARPA, the governmental department that researches crazy things that may eventually make it into the military, is currently working on an "ultrasonic curtain". In layman's terms, it's a sonic cloaking device designed to lower noise levels by at least 30db in military vehicles.
