摘　　要：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 new two-dimensional left-handed material based on double-triangled sructure is proposed. The simulation software HFSS is used to analyse the structure and its derivative structure. Results show that this type of structure can present left-handed properties when electromagnetic waves are incident on either perpendicularly or parallelly the plane of the substrate. And the general rule for this type structure is that： When the incident electromagnetic wave is in the perpendicular or parallel direction, and for each additional metal strip in the middle of the metal wires, the resonant frequency of the structure moves to higher frequencies around 0.5 or 4 GHz. These can be of reference values in further development of multi-dimensional left-handed material.
