Decoration of curved topological objects with an ultrathin layer of meta-atoms, which creates a conformal metasurface, allows the scattering wavefront to be modulated willingly. Here, we demonstrate adaptive conformal metasurfaces, which are composed of subwavelength dielectric TiO2 nano-posts on curved surfaces. Further, these surfaces support novel phenomena, such as focusing, tunable anomalous refraction, cloaking, and illusion (curved holography) in the visible range. The polarization-independent cloaking is demonstrated successfully by using these high-efficiency dielectric conformal metasurfaces. Besides, the metasurfaces's performance under small oblique angles of incidence angles was similar to its performance under normal angles of incidence. Conformal metasurfaces loaded on curved objects are promising platforms for applications in miniaturized optical systems, such as medical devices, wearable electronics, and communication devices.
