Metasurfaces play an important role in holographic imaging to flexibly manipulate and control electromagnetic wave fronts. However, metasurface‐based holograms present weaknesses in space utilization and efficiency. In this work, a 2‐bit coding metasurface based on double‐face copper‐cladded patterns on a single‐layer substrate is proposed, where the electromagnetic waves can be independently manipulated...
Driven by the increasing demands for high integrations and large information capacities, the low‐profile and multifunctional coding metasurfaces have drawn much attention. Here, a novel, single‐layer, low‐profile, and multifunction coding metasurface based on frequency and polarization multiplexing is proposed. Numerical and experimental results demonstrate that the proposed coding metasurface can...
