In article number 2100689, Changzhi Gu, Junjie Li, and co‐workers successfully fabricate a 3D bended metasurface with arrays of asymmetric split ring resonators using focused ion beam‐defined origami. Both giant circular dichroism (CD) and asymmetric chirality properties are realized simultaneously in the same metasurface, and the CD for the forward and backward incidence at mid‐infrared range are...
Chiral metasurfaces offer crucial opportunities to expand the application potential for chiral photonics, but its desired freely structural control and giant circular dichroism (CD) allow for more and greater challenges. Here, different from previous metasurfaces with single structural regulation, a kind of bifunctional chiral metasurface based on 3D bended asymmetric construction is proposed, which...
