摘要
左手材料（LHMs）是一种介电常数ε和磁导率μ同时为负值的电磁材料，近年来在实验上取得了突破性的进展，引起了当今物理学和电磁学的关注。文章介绍了左手材料的基本原理和微波频段左手材料的实现方法。总结了左手结构在微波频段的研究进展，展望了左手材料在微波器件和天线上的应用前景。
Left-handed metamaterials of which the dielectric constant and the magnetic permeability are simultaneously negative,are a kind of electromagnetism materials,So far,a lot of attention has been drawn to this area since some great progresses were made in the experimental study of LHMs.The basic principles of Left-handed materials and the methods to realize it in microwave frequency band are introduced, and the research progress of the LHMs in microwave frequency band is presented. Finally, the application prospects on microwave device and antenna are put forward with left-handed metamaterials.
