摘　　要：通过理论分析和实验仿真,研究了用双环开口谐振环对(doublesplit-ring resonator pairs,DSRRP)实现平面左手超材料的原理,用等效电路理论解释并描述了其负介电常数和负磁导率的产生机理,并对DSRRP在3维左手超材料设计的应用进行了探索性研究.结果表明,DSRRP可以实现小尺寸的平面左手超材料,此外,DSRRP还可以作为用以实现3维左手超材料负磁导率的3维各向异性磁超材料.By theoretical analysis and experimental simulation, planar left-handed metamaterials using double split-ring resonator pairs are studied in this paper. Simultaneous negative permittivity and permeability are described and explained by using equivalent circuit theory. Moreover,double split-ring resonator pairs used in the design of 3-dimensional left-handed metamaterials are also investigated. The results show that double split-ring resonator pairs can be used as planar left-handed metamaterials with small sizes and that double split-ring resonator pairs can be also used as 3-dimensional anisotropic magnetic metamaterials to realized negative permeability in 3-dimensional left-handed metamaterials.
