Abstract

All-metal metasurfaces are structural arrays composed of sub-wavelength metal units, which exhibit high efficiency and large bandwidth in phase manipulation of electromagnetic waves. Compared with metal-dielectric hybrid metasurfaces, all-metal metasurfaces have excellent thermal and mechanical properties, such as high-temperature resistance, high strength, and good ductility, which enable them to be applied in extremely complex environments such as high temperature and high pressure. In this paper, we briefly summarize the recent research progress based on all-metal metasurfaces. We mainly introduce their applications in the construction of highly efficient and multi-functional planar optical devices as well as multi-spectrum electromagnetic stealth, and provide an outlook of the future direction of its development.
