Velcroman1 writes: Invisibility cloaks and deflector shields, once a staple of popular science-fiction, are now the real deal, researchers say.

Company CEO and inventor Nathan Cohen issued a scathingly critical press release throwing very visible zingers — and claiming he invented it first. “[Their tech] makes you more, not less, visible,” Cohen said. The company says a patent-pending deflector shield built off a variant of the technology can divert electromagnetic radiation around an object — and they plan to show it off Friday in New York City, at the Radio Club of America.
