Researchers from the University of Cambridge, UK report for the first time the fabrication of a truly 3D metamaterial using polymers that assemble themselves into repeating structures of the required size and symmetry, as shown in the video below. The presented approach could pave the way for potential mass production of large-scale 3D optical metamaterials.
You can find more details on the work presented in the video in the article here.
