| 摘 要： | 通过将单回路镜像对称开口金属环结构印制在高介电常数基板上,实现了一种金属含量比传统负折射材料更少,"双负"通带比全介质负折射材料更宽的负折射材料.分析了高介电常数基板产生负介电常数以及"双负"通带形成的机理,通过仿真实验分析了影响"双负"通带的因素.通过制作样品验证了这一机理实现"双负"的可行性,理论分析与实验结果都表明这种方法可实现较宽频段内的"双负"通带.

| Abstract: | By printing single-loop mirror-symmetrical split-ring resonators on high-permittivity substrates, a type of negative index material was realized with less usage of metals and broader negative-index bandwidth than conventional negative index materials. The underlying mechanisms of realizing negative permittivity by means of high-permittivity substrates and of double-negative pass-band were analyzed. The influening factors on the double-negative pass-band were analyzed both numerically and experimentally. By experiments, the proposed method of realizing double-negative property was verified. Both the theoretical and experimental results show that broad double-negative pass-band can be realized using the proposed method. |
