共形超颖表面可以打破物体几何形状与光学功能之间的限制, 使散射波前得到任意的调制。文中展示了一种自适应的共形超颖表面, 该超颖表面由非手性镜面对称的Ω型金纳米天线组成, 可以集成在任意形状的基底上, 在可见光范围内(λ=450 nm)实现曲面全息。共形超颖表面的相位调制方法依赖于贝里相位, 通过旋转纳米天线的方位角, 可以在每个亚波长单元中进行连续的相位控制。这种共形超颖表面包裹在曲面拓扑物体上可以用于各种实际应用中, 如曲面透镜聚焦、隐身和安全打印技术。

Conformal metasurfaces can break the restrictions between the geometry of an object and its optical functionality and allow the scattering wavefronts to be modulated willingly. Here, it is demonstrated that adaptive conformal metasurfaces is composed of achiral mirror symmetry Ω-shaped gold antenna, which can be integrated on arbitrary substrate to achieve curved holography in the visible range (λ=450 nm). The underline modulation scheme of conformal metasurface relies on the Pancharatnam-Berry phase, which can be continuously controlled in each subwavelength unit cell by rotating the orientation angle of the antenna. Such conformal metasurfaces decorated on curved topological objects can be employed in various practical application such as curved lens focusing, invisibility cloaking, and security printing technologies.
