Ultra-thin camera lenses of the future could see the light of day

In the future, camera lenses could be thousands of times thinner and significantly less resource-intensive to manufacture. Researchers 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.
