Inverse-design and 3D printing combine to create groundbreaking metadevices
“As our technology gets smarter, it also gets smaller. Lately, this trend can be seen across a whole range of systems, from smart cars to cellphones to desktop 3D printers. But what of the entire data-sharing system itself? A group of researchers at Northwestern University have begun to investigate this topic precisely, as seen in a new study published in the academic journal Scientific Reports. Their first conclusions have been nothing short of astonishing.
The paper, titled “Inverse-designed broadband all-dielectric electromagnetic devices”, paints a portrait of a world where eyeglasses are impossibly thin, and a smartphone camera is so tiny that it’s invisible to the naked eye. In this world, sensors are highly aerodynamic, and able to conform to the exact angle and slope of an airplane wing. Materials can even act as invisibility cloaks, coating tanks to make them seemingly disappear. While it all may sound like the stuff of science fiction, this world may arrive sooner than we think…”
