Bidirectional Origami Inspiring Versatile 3D Metasurface (Adv. Mater. Technol. 8/2022). Issue 8 (10th August 2022) - Zheng, Ruixuan
Abstract : Bidirectional Origami In article number 2200373, Changzhi Gu, Junjie Li, and co‐workers demonstrate bidirectional origami based on focused ion beam (FIB)‐induced stress for various of materials, and the Monte Carlo simulations show that the key factor of bidirectional origami relies on the sputtering ratio for materials. Furthermore, a 3D chiral metasurface composed of bidirectional folded split ring resonators is designed and fabricated to realize a giant circular dichorism of 0.78/0.85 (Experiment/Simulation).
