Pentagon brass are said to be very interested in a new stealth invisibility cloaking technology recently announced by scientists.
The research team at the University of California-San Diego, Boubacar Kante, Li Yi Hsu and Thomas Lepetit, released a paper detailing their testing of the first working “dielectric metasurface cloak” – an invisibility cloak.
The cloak is a lightweight, material which manipulates electromagnetic waves which include the normal spectrum of visible light detectible to both the naked eye and radio waves. The device renders it undetectable by radar because radio waves simply reflect off the material.
Radar detects objects by bouncing electromagnetic waves off an object and then back to the receiver. The principle is very similar to bats’ use of echolocation, a radar-like ability, to help them “see”.
