2020年光学超材料热点回眸

Memorable sounds in the optical metamaterial in 2020

光学超材料一直是超材料学科中的重要组成部分之一,是超材料在信息科学领域中应用的重要体现。2020年,光学超材料领域的研究涌现出了一大批非常优秀的科技成果。围绕非线性光学超材料、人工智能超材料与光学超表面等方面回顾了光学超材料在2020年的研究热点。

As a new concept originated in early 21 st century, metamaterials have since attracted extensive attention of both scientific research and industry. Different from traditional materials, the properties of the metamaterials are created by artificial structures instead of intrinsic compositions of the materials, thus they exhibit many extrondinary properties beyond nature.Optical materials is one of the most important parts in this field, playing a significant role in information technology. In 2020,there were a lot of excellent research works in the optical metamaterials field. Here, we give a comprehensive review based on the works in nonlinear optical metamaterials, artificial intelligence metamaterials, and optical metasurface.
