Abstract :
In this paper, the surface roughness effects with Au particles which are simulated and discussed by solving a set of 3D Maxwell´s equations is studied. Both the experimental and numerical results of this study show significant identification of Rhodamine 6G (R6G) using the fabricated samples.
