Laser‐Printed Emissive Metasurface as an Anticounterfeiting Platform

Optical security is a promising application of metasurfaces because light has large degrees of freedom in metasurfaces. Although many different structures/materials are proposed for this purpose, the fabrication of dynamic metasurfaces in a straightforward and scalable manner, while maintaining a hi...
