ALSO CALLED: Advanced Research Projects Agency, DARPA, ARPA
DEFINITION:  A cloak of invisibility is a method of rendering physical objects undetectable or invisible. Researchers from the United States and England have developed a prototype for a cloaking device that can hide an object approximately 30 centimeters (1 foot ) in diameter. The device works by producing a mirage, in a manner similar to the way a layer of heated air causes reflection or refraction of light to  …

DEFENSE ADVANCED RESEARCH PROJECTS AGENCY DEFINITION (continued): …  create an illusion that can conceal objects on the earth's surface when viewed from a distance at a grazing angle.In the microwave portion of the radio-frequency (RF) spectrum, where most radar systems operate, cloaking differs from stealth technology. A stealth aircraft evades radar detection by presenting a minimal profile for reflecting microwave electromagnetic fields. Cloaking actually diverts electromagnetic waves around the object. This can completely eliminate its image at a specific wavelength. At visible-light wavelengths, such a process may cause distortion of images directly behind …
