摘要
研究了左手材料的传输和反射特性,介绍了所仿真的样品形式和测量系统,并采用高频构造仿真方法(HFSS)在已有自由空间宽频测量的基础上进行理论仿真。结果表明:S参量的数字仿真与实验测量结果在宽频条件下达到了较好的一致性;测量中产生的损耗主要归因于铜线结构有限的电导率;理论上左手材料的最佳无损工作频段应高于谐振环的谐振频率。
This paper presents the research on transmission and reflection characterization of left-handed materials. It introduces correlative sample patterns and the measuring system. Using high frequency structure simulator(HFSS) method, based on former broad-band measurement which got a high uniform between simulation and measurement of S parameters. Simulation of insertion loss demonstrates that losses in measurements mainly attribute to finite conductivity of copper wire, and optimal-lossless frequency region must be higher than resonance frequency of split ring resonators in theory.
