Standing metallic nanostripe array structure

摘要

We fabricated the standing metallic nano-stripe array structure on the thin ITO layer with a very narrow width and a relative high height of the stripe by using the electron-beam lithography and Ar ion milling process. The polarization properties were investigated as the period and the incident angle are varied. In transmission spectra of the TE polarization, the resonance with Fano-like resonance was observed. In case of TM polarization, there's no resonance near normal incidence because the electric field is perpendicular to the very thin metallic grating.
