  • Traditional optical lenses and optical systems implement electromagnetic wave control based on the light propagation effect. So they usually suffer from the bulky size. Recently, metasurfaces comprised of artificial subwavelength structures have been widely studied, since they take great advantages of their subwavelength thickness and provide arbitrary control of electromagnetic waves. Here, the electromagnetic wave control mechanism is introduced. Then, we analyze the monochromatic aberrations and chromatic aberrations of the metalens and the corresponding image quality evaluation methods. Also, we discuss the research progress and applications of metalens for imaging. The exist problems and future goals are pointed out at the end of the review. Based on the advantages of portability and a high degree of design freedom, metalens are expected to replace the traditional imaging devices in many applications. High efficiency, large field of view, broadband, reconfigurable and tunable imaging devices based on metasurfaces will help in important future development directions.
