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.
A cloaking device is one where the purpose of the transformation is to hide something, so that a defined region of space is invisibly isolated from passing electromagnetic fields (see Metamaterial cloaking [1] [2]) or sound waves. Objects in the defined location are still present, but incident waves are guided around them without being affected ...
Cloaking applications which employ metamaterials alter how objects interact with the electromagnetic spectrum. The guiding vision for the metamaterial cloak is a device that directs the flow of light smoothly around an object, like water flowing past a rock in a stream, without reflection, rendering the object invisible. In reality, the simple ...
The concept of a cloaking device has a lot of appeal and though we're far from being able to make 3D objects invisible to the human eye, researchers continue to develop new ways in which to shield ...
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.

Invisibility Cloak may refer to: Cloak of invisibility, a theme that has occurred in fiction Invisibility cloak (Harry Potter), a specific instance in the Harry Potter series; Cloaking device, technology for partial or full invisibility to parts of the electromagnetic or acoustic spectrums Metamaterial cloaking, a type of cloaking using ...
The "lifecasts" are now done with high-tech scanners that can map a person's face in minutes. A 3D printer is then used to turn the scans into a mold of the person's face.
