An international team from the Institute of Electronics, Microelectronics, and Nanotechnology (IEMN), the Polytechnic University of Turin, Empa, and the Norwegian University of Science and Technology has found a way to create adaptable metamaterials. The researchers demonstrated a polymeric, 3D-printed, elastic metamaterial whose transmission spectrum could be deterministically tuned by illuminating it in a targeted manner with a laser beam. Using a photopolymerization-based 3D-printing technique, the researchers made a light-responsive elastic metamaterial consisting of a linear array of squared pillars arranged on a slab waveguide. The waveguide was made out of a polymer that was charged with molecules reactive to blue light. The…READ MORE
