我们实验证明了一种基于偶极和双四极耦合的方法来构建支持多光谱等离子体激元诱导透明的平面超材料。该结构由两根短银线（偶极）和两根长银线（双四极）组成。偶极和双四极之间的面内耦合导致即使在偶极的吸收线宽上也存在两个透射窗口。这种现象是很好地描述和理解的数值分析和一个经典的振荡器模型。(C)2014年美国光学学会
We experimentally demonstrated an approach based on dipole and dual-quadrupole coupling to construct a planar metamaterial supporting multi-spectral plasmon induced transparency. The structure consists of two short silver wires (dipole) and two long silver wires (dual-quadrupole). The in-plane coupling between the dipole and the dual-quadrupole leads to two transmission windows even in the absorbance linewidth of the dipole. This phenomenon is well described and understood by numerical analyses and a classical oscillator model. (C) 2014 Optical Society of America
