Invisible Drones Will (Not) Appear Over Your Town

An invisibility cloaking material designed by electrical engineers at the University of California, San Diego uses a Teflon substrate, studded with cylinders of ceramic. It is very thin and does not alter the brightness of light around concealed objects.


(The cloak: thin Teflon sheet (light blue) embedded with small ceramic particles (dark blue))

The Teflon has a low refractive index, while the ceramic’s refractive index is higher, which allows light to be dispersed through the sheet without any absorption. [1] Compared to an invisibility cloak, this technology has not only the ability to conceal, but the ability to increase optical communication signal speed and to collect solar energy.

The goal of this design is to create devices that make any object appear invisible by scattering the electromagnetic waves, such as light and radar, off an object making it less detectable to these wave frequencies. Metamaterial that surrounds the target is able to force light to bypass a region of space, which effectively “cloaks” the object, making it isolated from incoming electromagnetic waves...

Having the ability to create ultimate stealth protection for anything over a battlefield or warzone provides enormous military advantage over the adversary. In theory, creating a cloaking device would be used to conceal larger objects. This cloaking device would be valuable to many technologies, including unmanned air vehicles (UAVs) due to the capability to disappear from view and leaving no visual, electronic or infrared signature for an enemy to detect.

'Doc' Smith discussed the same idea in his famed 1934 novel Triplanetary:

"This structure, floating in a planetary orbit, was designed by me and built under my direction. It is protected from meteorites by certain forces of my devising. It is undetectable and invisible--your detectors do not touch it and light-waves are bent around it without loss or distortion. I am discussing these points at such length so that you may realize exactly your position. As I have intimated, you can be of assistance to me if you will."
