Circular polarizers that selectively transmit only one handedness of circular polarization are useful for imaging and wireless communications. Conventional circular polarizers involve 3D chiral structures, which impose fabrication challenges, while typically introducing chirality within a limited bandwidth. To overcome the limitations associated with conventional non‐planar designs, a three‐layer...
Origami metasurfaces have emerged as a versatile platform for dynamically manipulating electromagnetic waves due to their numerous advantages, including cost‐effectiveness, lightweight nature, and diverse structural transformations. They are particularly well‐suited for reconfigurable chiroptical responses that can find utility in various applications. However, current research has primarily focused...
