摘　　要：利用电磁波传递能量和信息一直是备受人们关注和重视的研究课题,因为它在通讯、能源、环境、医药等多应用领域中都扮演重要的角色。近年来,随着微纳米制造技术的进步,超材料的出现为解决传统电磁技术的瓶颈问题(如光路体积大、结构复杂、功能单一等问题)提供了新思路和新机会。得益于超强的电磁场调控能力,这些材料不仅能够实现传统光学元件的诸多功能,而且还能实现很多自然界不存在的、奇异的电磁响应和特性。本文将结合作者近年来的研究工作,对超材料的研究进展和发展趋势进行综述,主要思路是根据调控的电磁波自由度对超材料进行分类和阐述。最后作者还将介绍基于相变材料的主动调控超材料。Usage of electromagnetic waves for transmitting energy and information has always been a research topic of great concern and interest, owing to their important role in many application fields, such as communication,energy, environment, medicine and so on. In recent years, with the development of micro/nano-fabrication technology, metamaterials have emerged and provided new ideas and opportunities to solve the bottleneck problems of traditional electromagnetic technology, such as large volume of optical-paths, complex structure, single function etc.Thanks to the strong ability to control electromagnetic waves, these materials can not only enable various functions of traditional optical elements, but also bring out some novel electromagnetic responses that do not exist in nature.Herein, the recent advances in metamaterials are briefly reviewed and classified from the viewpoint of the degrees of freedom of electromagnetic waves. At last, we will discuss something about active metamaterials based on phase transition materials.
