Cloak of Invisibility: US Scientists Develop Anti-Radar ‘Skin’

A team of Iowa University experts has developed a stretchable “skin” that exceeds the radar-wave deflection qualities of all existing materials, including those used on military aircraft, N+1 online paper wrote.

Dubbed as “meta-skin” the new material consists of several layers of silicon elastomers each consisting of 225 identical resonators filled with galinstan, a metal alloy of gallium, indium and tin.

During a series of tests the resonators — small rings 2.5 millimeters across and half a millimeter thick – suppressed up to 75 percent of radar waves in the frequency range of 8 to 10 gigahertz.

According to Iowa University’s website, the developers of the meta-skin technology expect it to replace all existing stealth technology and hope that it may someday help create a cloak of invisibility.
