Efficiency of Emission from Surface Plasmon Waves of Ag Films for Different Pre-Coated Layers
The attenuated total reflection technique was used to excite surface plasmon. We have measured the efficiencies of the surface plasmon energy emitted through surface roughness into air side, for prism/LB film or Ag film /Ag film/ air and prism/Ag film/air structures. Depending on the distribution of scattering light intensity, the surface roughness parameters, i. e. the transverse correlation length σ and the surface corrugation depth δ of air/Ag film interface were simultaneously evaluated. Then we calculated the emission efficiency of the surface plasmon polariton energy from σ and δ. The calculated efficiency corresponds with that of experiment.
