Kurzfassung:
Huygens metasurface, as a subcategory of metamaterials, shows great potential in the capacity and efficiency of electromagnetic wave manipulation within a subwavelength scale. Here, the transmission-type Huygens metasurface is demonstrated for complete and independent control of orthogonally polarized transmitted waves by constructing pairs of crossed electric and magnetic resonances in three-sheet meta-atoms as the building blocks for holographic imaging. Under incoherent horizontally and vertically polarized illuminations, two designated holographic images with negligible mutual interferences are accomplished with at least 62.95% measured imaging efficiency and 63.53 signal-to-noise ratio, respectively. This work addresses several major issues in traditional polarization-multiplexed holography with regard to transmission-coefficient manipulation capacity, image fidelity, and simple fabrication technique, empowering advanced research and applications in polarization-selective microwave devices and information processing.
