Metasurfaces: Design Principles and Application Challenges

Consisting of sub-wavelength scatterers or holes arranged on a plane, the metasurface, as a two-dimensional form of the metamaterial, permits flexible and efficient modulation of the amplitude, phase, polarization and other characteristics of the light with an unprecedented degree of freedom, which is expected to break through the limitations of traditional optics and realize ultra-light, ultra-thin, high-performance, and novel-functional optical devices. In recent years, metasurfaces have attracted increasing research interest in both academia and industry, and a wide range of applications have been achieved in the field of imaging, holography, quantum optics, displacement metrology, virtual reality, optical encryption, and ultrafast optics. Based on the elucidation of the basic design principles of metasurfaces, this review covers the main development directions, research progress, and challenges of current metasurface applications.
