Achieving multitasking wavefront manipulations at multiple frequencies within a planar meta‐device is pivotal for increasing data density and functionality diversity yet still challenging in integrated devices. Considering both high efficiency and compactness, herein, a high‐efficiency reflective metasurface based on single‐cell meta‐atoms with independent complex‐amplitude modulations at three distinct frequencies under the circularly polarized incidence is demonstrated, which can facilitate the formation of three mutually orthogonal channels with three distinctive functionalities. As a proof‐of‐concept demonstration, a tri‐channel metasurface is designed and verified through both numerical simulation and experiment, where channels 1, 2, and 3 implement a dual‐vortex‐beam generator, a quad‐focus metalens, and a meta‐hologram at three different frequencies, respectively. The simulated results and the measured results have very good agreements, validating the proposed tri‐band single‐cell metasurface design strategy. The proposed method can open new opportunities to improve the information density and has promising prospects in image displays, communication systems, and optical storage. |
