A New Engineered Stealth Metamaterial is the Blackest Ever
Abstract:
A new blacker-than-black metamaterial absorbs almost all the light that hits it, heralding a new breed of stealth technology.
The material's internal structure absorbs almost all the electromagnetic radiation in a particular range, New Scientist reports. Ordinary black objects, by contrast, always reflect a bit of light. The material could be applied to all parts of the electromagnetic spectrum, meaning it could be used to make materials invisible to radar.
Designed by Evgenii Narimanov of Purdue University, Mikhail Noginov of Norfolk State University in Virginia and their colleagues, the material consists of silver nanowires embedded in very thin 0.4-inch aluminum oxide squares. Their array-like structure gives them their unusual properties, New Scientist says.
