Saw a version of this article in our local paper and found it rather hard to believe but since I know very little of the technology, it http://www.extremetech.com/extreme/143353-canadian-camouflage-company-claims-to-have-created-perfect-invisibility-cloak-us-military-soon-to-be-invisible may well be possible.
Quotes:
Now, we’ve written about invisibility cloaks in the past, but these have generally been very small, lab-based experiments that only work with very specific wavelengths of light. These invisibility cloaks generally work by bending light around an object using metamaterial waveguides — think of them as optical paths that negatively refract light, so that their detour around the object can’t be discerned. So far, we have only managed to develop metamaterials that bend specific wavelengths of light — so the object might be invisible to microwaves or infrared, but not both. Quantum Stealth reportedly works across the entire range of visible light, and infrared too. If this is really the case, Quantum Stealth completely redefines the state of the art.
In theory, Quantum Stealth works by bending light around the target, and Cramer certainly uses the right words to support his case — nanotechnology, metamaterials — but it’s still very hard to believe that a lone inventor in Canada has actually succeeded in creating an invisibility cloak. It’s not impossible, but it’s improbable. I want to say that there’s a clue in the name — that Quantum Stealth somehow uses some neat glitch in quantum mechanics to provide invisibility — but really, it’s probably just hyperbole, like the company’s name. If Quantum Stealth really exists, though, you’d assume that the US military would be quick to flaunt its new toy. After all, there’s nothing more terrifying than an invisible army.
