Abstract
As a branch of metasurfaces, metalens have demonstrated unparalleled potential in optical manipulation and imaging shaping. By altering the structure of meta-atoms, metalens can achieve various functions, such as diffraction-limited focusing and aberration correction. This paper introduces the principles and modulation methods of metalens, categorizing them into plasmonic and dielectric types based on the materials used. It also covers tunable metalens and achromatic metalens, highlighting some of the latest advancements in the field. The aim of this paper is to provide readers with a comprehensive understanding of metalens and offer new ideas and methods for designing high-performance optical systems in the future.
