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.

This is an effect of embedding purposely designed electromagnetic sources in the metamaterial. [37] As discussed earlier, the fields produced by the metamaterial are compressed into a shell (coordinate transformations) surrounding the now concealed volume.

Suggest division into two sections: "Invisibility in Physics/Technology" and "Invisibility in Fiction", as the only real-world "cloaking" device that exists has been made by physicists (and some electrical engineers), and it is going to remain this way for the forseeable future.
