摘要
负折射率材料作为一种具有奇异特性的新型材料,已经成为人们关注的热点。该文主要介绍了负折射率材料的特性,着重阐述了实现负折射的3种主要方法:左手介质、手征介质、光子晶体,其中,用手征介质和光子晶体方法实现负折射最大的优点是可以使损耗很低。另外,叙述了负折射材料的发展状况和前景展望。
As new materials with special characteristics, the negative refractive materials have been a focus. This paper introduces the unique characteristics of negative refraction, and expounded deeply the three ways to realize negative refraction, which are left-handed medium, chiral medium and photonic crystals, among them, the biggest advantage of the last two ways to realize negative refraction is low wear and tear. At last, it describes the development situation and prospects of the negative refraction materials.
