Metasurfaces are two-dimensional metamaterials with unprecedented capabilities for manipulating light through their ultrathin and flat architectures.Originally, metasurfaces employed subwavelength resonators to control the local phase of light.Later, their design was extended to nonresonant geometric (Pancharatnam-Berry) phases and dynamic propagation phases.The constituent materials of metasurfaces have extended from metals to all-dielectric to reduce the losses.Metasurfaces have provided numerous functionalities such as beam engineering, waveplates, polarizers, and holograms [1].One popular application is metalens imaging, which promises extremely wide uses in optical systems [2].Although the imaging performances of metalenses (e.g., efficiency, working bandwidth, field of view) have been improved by various methods, they are usually constrained by each other.Therefore, the comprehensive performance of today's metalenses is still inferior to the traditional refraction lenses and compound lenses.
