【摘要】 特异材料(metamaterials)是指自然界中不存在的具有奇异电磁特性的人工结构,通常指的是介电常数和磁导率同时为负值的左手材料(lefthandedmaterials).自从2002年利用传输线制备左手材料的思想被提出后,人们对基于传输线的特异材料进行了大量的研究.文章着重概述了近年来人们所提出的几种典型的传输线特异材料的结构、制备方法、实现左手性的原理以及各自的特点.更多还原

【Abstract】 Metamaterials are artificial structures exhibiting novel electromagnetic properties but not commonly found in nature, and they are generally known as left-handed materials with simultaneously negative permittivity and permeability. Much progress has been made during the past few years on the development of metamaterials based on the transmission-line mechanism since it was first proposed in 2002. The structure, preparation, principle of operation and properties of several typical transmission-line metamaterials are discussed.更多还原
