Surface Plasmon Interference with Two-Slit Metal Structure

Article Preview

Abstract:

We present a kind of surface plasmon interference phenomenon in two-slit structure. The simulation results show that the interference phenomenon will become more obvious for the two-slit structure with -shape slit than for the one with T-shape slit. And the interference effects can be improved by increasing the width of -shape slit shoulder. These results will be useful to design novel surface plasmon-based optical devices.
