Harry Potter's 'invisibility cloak' a reality now?

Want to hear what your wife is really saying about you? Stroll right infront of her and that too invisible. Once occurred in fiction, Harry Potter's invisibility cloak is almost a reality now.

HyperStealth Biotechnology, a Canadian company claims to have come with camouflage technology known as Quantam Stealth camouflage material, which renders its wearers invisible by bending light waves around them. It blocks the subject from being seen by visual means but also keeps them hidden from thermal scans and infrared.

Quantum Stealth is a material that renders the target completely invisible by bending light waves around the target. The material removes not only your visual, infrared (night vision) and thermal signatures but also the target's shadow. The cloak is still under development, and the pictures circulating in the media are rendered in photoshop for security purposes.

Guy Cramer, President/CEO of Hyperstealth Biotechnology Corp, asserts "We cannot show the Media the concept, for security issues we cannot show the actual technology. With the real material you would only see about 5% of the shadow on her and the ground as we have determined a 95% reduction of shadow in testing."

Two separate command groups within the U.S. Military and two separate Canadian Military groups as well as Federal Emergency Response Team (Counter Terrorism) have seen the actual material so they could verify that authenticity of the claims. Hyperstealth, states "Both the U.S. and Canadian military have confirmed that it also works against military IR scopes and Thermal Optics."

It's not for the first time, that the idea of invisible cloak has surfaced. A year back in 2011, NSF Nanoscale Science and Engineering Center (NSEC), University of California, claimed to have developed an invisible carpet cloak. The reflective "carpet cloak" is made out of layers of silicon oxide and silicon nitride mashed in a special pattern that conceals an object under the layers, and bends the light waves falling on it in such manner that the cloak appears flat and smooth like a normal mirror.

As per the research papers, the carpet is capable of making an object undetectable by visible light. The cloak is designed using quasi conformal mapping and is fabricated in a silicon nitride waveguide on a specially developed nanoporous silicon oxide substrate with a very low refractive index (n<1.25).
