Conformal metasurfaces can break the limitation between an object’s geometric shape and its optical function. and significantly improve the optical properties of any curved object. This extends the capability of metasurfaces to components with arbitrary shapes. In previous research on conformal metasurfaces, polarization multiplexing technology was not applied, limiting the multi-functionality of these metasurfaces for different polarization channels. A polarization-sensitive conformal metasurface on a curved substrate was proposed by us.. By designing the unit structures of the conformal metasurfaces based on propagation phase, such metasurface can achieve different optical functions for incident light with different polarization states, and achieve functions such as curved holography and optical stealth. With high flexibility, the conformal metasurface design can be embedded in various non-planar systems to achieve multi-functionality, and has broad application prospects in areas such as military security and wearable electronic devices.
