Ukraine has reportedly developed a real-life "invisibility cloak" that can hide soldiers from thermal cameras thanks to its unique properties that block heat signature radiation.The images show ...
Rochester Cloak is a cloaking device which can be built using inexpensive, everyday materials. John Howell, a professor of physics at the University of Rochester, and graduate student Joseph Choi developed the device, which features four standard lenses that allows an object to appear invisible as the viewer moves several degrees away from the optimal viewing positions.
An operational, non-fictional cloaking device might be an extension of the basic technologies used by stealth aircraft, such as radar-absorbing dark paint, optical camouflage, cooling the outer surface to minimize electromagnetic emissions (usually infrared), or other techniques to minimize other EM emissions, and to minimize particle emissions from the object.
Scientists Take Step Toward Invisibility, Australian Broadcasting, Reuters with Invisibility Cloak a Step Closer, and the (Raleigh) News & Observer with 'Invisibility Cloak a Step Closer. [49] On November 6, 2006, the Duke University research and development team was selected as part of the Scientific American best 50 articles of 2006. [50]
If you ever hoped an invisibility cloak was a real thing, you will be happy to know that one now exists. Unfortunately, it will only work on something incredibly small, specifically microscopic.

Theories of cloaking discusses various theories based on science and research, for producing an electromagnetic cloaking device.Theories presented employ transformation optics, event cloaking, dipolar scattering cancellation, tunneling light transmittance, sensors and active sources, and acoustic cloaking.
In 2003, complex (both real and imaginary parts of) negative refractive index [22] and imaging by flat lens [23] using left handed metamaterials were demonstrated. By 2007, experiments that involved negative refractive index had been conducted by many groups. [3] [15] At microwave frequencies, the first, imperfect invisibility cloak was ...
