New Nanoparticle-Based Metasurfaces for Future Camera Lenses

In the future, camera lenses could be thousands of times thinner and significantly less resource-intensive to manufacture. Researchers from Chalmers University of Technology, Sweden, now present a new technology for making the artificial materials known as 'metasurfaces', which consist of a multitude of interacting nanoparticles that together can control light. They could have great use in the optical technology of tomorrow.
