摘要：
A novel kind of structure of negative index metamaterial (NIM) is proposed, which consists of the unit cells with metal wires and three split ring reso-nators (SRRs) located on the opposite sides of a dielectric substrate. The electromagnetic parameters obtained by S-parameter retrieval method demonstrate that the structure can exhibit multiple negative index bands from C to Ku microwave bands. Besides, numerical simulation shows that the main structure parameters, such as the length and the width of the metal wire, the width of SRRs and the space between the inner and outer rings of the middle SRRs, have different influences on negative index bands. Which implying that the structure possesses a stable characteristic of the multi-band negative refraction within a certain range of the selected parameters. ©, 2014, Guangxue Xuebao/Acta Optica Sinica.
