基于两宽金属条中间引入两交叉细长金属线的双三角形结构,提出了一种新型二维超材料结构.利用HFSS软件对该结构及其衍生结构进行仿真分析,结果表明:该类形结构在电磁波垂直和平行两种入射情况下都能实现双负特性,通过比较分析归纳出该类形结构的一般规律:电磁波以垂直和水平两种方式入射时,中间引入的金属线个数每增加一根,结构的谐振频率向高频方向分别移动0.5 GHz和4 GHz左右.对多维左手材料的发展提供了参考.
A novel two-dimensional metamaterial structure was proposed based on the double-triangle structure with two crossed metal wires in the middle of two wide metal strips. The structure and its derivative structure were simulated by HFSS software. The results show that this kind of structure Double-negative characteristics can be achieved under both vertical and parallel incidence of electromagnetic wave. The general law of this type of structure is concluded by comparison and analysis. When the electromagnetic waves are incident on both the vertical and horizontal planes, the number of wires introduced in the middle increases One, the resonant frequency of the structure is shifted to the high frequency direction by about 0.5 GHz and about 4 GHz respectively, which provides a reference for the development of multidimensional left-handed materials.
