Simulation of a hypothetical cloaking device. Normally, incident light waves on an object are absorbed or reflected, causing the object to appear visible.

With the cloaking device active, light is 'deflected' around the object to make it appear as if it did not exist, rendering it invisible.
A cloaking device is a hypothetical 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[1] 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.[2] However, over the entire spectrum, a cloaked object scatters more than an uncloaked object.[3]
