为了改进传统的开口谐振环-导线( SRRs-wire)结构电磁特性，利用不同大小的开口谐振环所产生不同负磁谐振频率点的特点，设计了同向开口双环的SRRs-wire结构，并给出了其等效电磁参数反演结果。通过增加其单元结构的金属短线的个数实现了双通带左手特性；同时通过改变外环为U型环降低了内外环的相互耦合。利用内外谐振环间具有弱耦合的特性，提高了高频左手通带的带宽，同时可以较方便地调节双通带工作频率点，具有很好的可调性。

In order to improve the magnetic performance of traditional SRRs-wire,by taking advantage of the characteristic with different sized split ring generated different negative magnetic resonance frequency,designed a new SRRs-wire structure with two different sizes but the same direction double split ring resonators. The retrieved parameters for the structure are also presented. By increasing the number of the metal wire in the unit structure obtained the dual-band left-handed materials,meanwhile by changing the outer ring to U-shape ring reduce the mutual coupling of the inner and outer ring to improve bandwidth of the high-frequency portion and make sure the struc-ture has a good tunability.
