本文讨论了一种单边结构左手材料，其对称的成对开口环谐振器通过切割线直接连接。这种连接的单侧左手材料可以表现出低损耗和宽的负折射通带。通过与面内和离面情况的比较，反演结果与仿真结果吻合较好，验证了上述结论[T。Koschny，M. Kafesaki，E. N. Economou和C. M. Soukoulis，Phys. Rev. Lett. 93，107402（2004）]。
A single-sided structure left-handed metamaterial (LHM), of which the symmetric paired split-ring resonators are connected directly through cut wires, is discussed in this paper. This connected single-sided LHM can exhibit a low loss and broad negative refraction passband. Good agreement of the retrieved result and the simulated result verify the above conclusion by comparison with the in-plane case and the off-plane case [T. Koschny, M. Kafesaki, E. N. Economou, and C. M. Soukoulis, Phys. Rev. Lett. 93, 107402 (2004)].
