摘要
阐述了左手材料的基本概念和性质,介绍了目前几种常见金属基元左手材料的结构、基本原理及特点,综述了左手材料近年来的研究动态及发展前景,指出左手材料要得到应用必须向低损耗和宽带宽方向发展。
The basic concepts and properties of left-handed materials are expatiated, the unit cells, principles and properties of several metallic left-handed materials are introduced. Briefly the latest advances and prospects of left- handed materials are introduced. For practical applications, it will be beneficial to develop LHM＇s with increased frequency bandwidth response and lower losses.
