摘要
对双金属环阵列结构产生负磁导率的机理进行了分析,在此基础上,尝试采用单金属环阵列结构来构造负磁导率材料.给出了单金属环阵列结构的负磁导率特性,研究了该材料负磁导率频率区间与各参数变量之间的平移特性.对单金属环阵列结构进行了改进,得到了一种体现负折射率效应的准Ω结构的复合介质.
Based on the analysis of the negative permeability properties of double split-ring-resonator array （SRRA）, a simplified structure called single SRRA was proposed and demonstrated. The negative permeability properties of single SRRA are confirmed by software simulation, and the relationship between frequencies intervals corresponding to the negative permeability and single SRRA＇s structured parameters was investigated. Finally, the structure of single SRRA was improved by a quasi-Ω-like metallic pattern and a compound material with negative index of refraction was obtained.
