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).
