Current microwave metasurfaces predominantly suffer from the disadvantages of optically opaque and phase-only modulation, which inevitably hinder their application potential. Herein, we have proposed a simple but efficient strategy for designing multifunctional metasurface that is capable simultaneously achieving visible transparency amplitude–phase manipulation. The designed meta-atom consists metal-frame-based H-shaped resonator metallic mesh layer separated by transparent dielectric substrate, enabling eight-level phase modulation with π/4 interval continuous amplitude covering range 0–0.9 at 16 GHz. As proof-of-concept demonstration, spatially multiplexed complex-amplitude hologram utilizing simulated experimentally validated. results show two distinct holographic images can be reconstructed in different imaging planes, measured average optical transmittance attains 63.7% wavelength 400–800 nm. Our design paves way to an expected great potential scenarios requiring both wavefront control.
