中文摘要：
开口谐振单环（Split Single Ring Resonators，简记SSRRs）和开口谐振环（SRRs）一样可以激励磁谐振，从而实现负的磁导率。提出在SSRRs结构中引入平行于其开口边的金属线的方法设计了新的磁谐振单元，研究了金属线的引入对谐振频率以及负磁导率特性的影响。数值模拟结果表明：随着金属线长度，的增加，SSRRs的谐振频率随之减小；随着金属线与开口边的间距d的增加，SSRRs的谐振频率随之增加。金属线的加入不会对SSRRs的负磁导率特性产生重要影响，改变金属线的结构参数可以实现μ〈0频段的调控。所提出的新的磁谐振单元对于新型负磁导率材料和新型左手材料的设计具有重要的实际意义，也为新型无线通信材料的实现提供了可能。
英文摘要：
Both the Split Single Ring Resonators （SSRRs） and Split Ring Resonators （SRRs） can be used as a negative permeability medium near its magnetic resonance frequency. A new design for magnetic resonance structures has been proposed by introducing a metal wire into the common SSRRs. The effects of metal wire on the transmission characteristics of SSRRs are numerically investigated. The results show that the resonance frequency of SSRRs decreases with the length of metal wire. The metal wire has no significant influence on the negative permeability of SSRRs. It is also proved that negative permeability could be tuned by controlling the distance between the metal wire and SSRRs. The new magnetic resonance structures proposed in this paper are of great practical values in designing new kinds of negative permeability materials and left-handed materials and make the new wireless communication materials practicable.
