开口谐振环(SRRs)结构可以激励磁谐振,实现负的磁导率.提出在SRRs两环间隙内引入相对交错的金属短线,并研究了金属短线对谐振频率的影响.结果表明:随着金属短线数目的增多,谐振频率显著降低,同时金属短线的结构参数如长度、宽度及间距也会对谐振频率产生影响.最后验证了金属短线的引入对减小器件尺寸有明显作用,且不因介质基底的存在而受到影响.新型磁谐振单元可为今后超材料的设计及实际应用提供新的参考.
The structure of SRRs can excite magnetic resonance and achieve negative permeability.It is proposed to introduce relatively short metal short-circuits in the two-ring gap of SRRs and to study the effect of metal short-circuits on the resonance frequency.The results show that with the metal The increase of the number of short lines and the decrease of the resonance frequency significantly affect the resonant frequency of the metal short-circuit, as well as the structure parameters such as length, width and pitch of the metal short-circuit.Finally, it is verified that the introduction of metal short- The existence of the substrate is affected.The new magnetic resonance unit can provide a new reference for the design and practical application of metamaterials in the future.
