A cloaking device is a theoretical or fictional stealth technology that can cause objects, such as spaceships or individuals, to be partially or wholly invisible to parts of the electromagnetic (EM) spectrum.
Fictional cloaking devices have been used as plot devices in various media for many years.
Developments in scientific research show that real-world cloaking devices can obscure objects from at least one wavelength of EM emissions. Scientists already use artificial materials called metamaterials to bend light around an object.

Famous quotes containing the word device:
“A bracelet of bright hair about the bone,
Will he not let us alone,
And think that there a loving couple lies
Who thought that this device might be some way
To make their souls, at the last busy day,
Meet at this grave, and make a little stay?”
—John Donne (1572–1631)
