摘要:

介绍了一种具有两个通带的新型混合左右手传输线,以及混合左右手材料传输线的传输特性和分析方法。该左手材料(Left-Handed Metamaterials,LHMs)在通带内呈现介电常数和磁导率同时为负的特性,两个通带分别出现在2.8 GHz和5.8 GHz处。通过仿真得到了色散曲线,折射率,等效介电常数和等效磁导率,从理论上验证了左手特性的存在。

关键词: 左手材料;复合左右手;双左手频带;色散曲线

Abstract:

The paper gives an introduction to a novel composite right/left-handed transmission line (CRLH-TL) meta-material with two pass bands as well as its operation and analysis method.In this meta-material,the permittivity and permeability are both negative.The two pass bands of the CRLH-TL exist at 2.8 GHz and 5.8 GHz,respectively.Simulation yields dispersion curves,index of refraction,permittivity and permeability,theoretically verifying the existence of left-handed metamaterials.

Key words: left-handed;quad band;backward waves;dispersion curves
