Theoretically Analyzed Optical Property of Silver Nanowire on a SiO<sub>2</sub> Layer

We demonstrate a silver nanowire (AgNW) grating placed on a SiO<sub>2</sub> layer. Comparing with the transmission spectra of the AgNW grating or the SiO<sub>2</sub> layer only, an obvious transmission dip is observed in our proposed structure. The transmission dip is caused...
