Abstract

Surface plasmon excitations with different nanostructure modulations on the interface between metal and dielectric were interesting to investigate. The study was performed by measuring optical transmission through perforated metallic thin film. Experimental observations on dependences of periods, depths, and widths of nanostructures on the transmission of gold film were reported. Furthermore, simulations by finite difference time domain (FDTD) method were used to predict the variations of transmission and reflection with periods.
