摘要:
Fano interference of metallic nanostructure is an effective way to reduce the irradiation loss and improve the spectral resolution. A Pi-shaped gold nano-trimer, which is composed of a gold nanorod and two gold nanorices, is presented to investigate the properties of Fano resonances in the visible spectrum by using the finite element method ( FEM). The theoretical analysis demonstrates that the Fano resonance of the Pi-shaped gold nano-trimer is attributed to the near-field interaction between t ...More
