A cloak of invisibility is an item that prevents the wearer from being seen. In folklore, mythology and fairy tales, a cloak of invisibility appears either as a magical item used by duplicitous characters or an item worn by a hero to fulfill a quest.
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.

[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.

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.
This idea, commonly known as the Invisibility cloak, has stimulated much recent work in the field of metamaterials. [23] In 2009 he and Stefan Maier received a large grant from the Leverhulme Trust to develop the ideas of perfect lens and invisibility cloak in the optical range of light. [24]
