    Tunable Photosensitive Metamaterials Could Improve Elastic Wave Control

    Article obtained from Photonics RSS Feed.

    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…
