"We put a thin layer of this plastic on a glass plate and, using a well-established technique called electron-beam lithography, we can draw detailed patterns in the plastic film, which after development will form the metasurface. The resulting device can focus light just like a normal camera lens, but it is thousands of times thinner - and can be flexible too," says Daniel Andrén, a PhD student at the Department of Physics at Chalmers University of Technology and first author of the scientific article recently published in the journal ACS Photonics.
