摘要：
A comparative study of surface plasmon polaritons (SPP) on thin Ag films of varying intrinsic (as evaporated) surface roughness was carried out using three well known complementary spectroscopies; the Attenuated Total Reflection (ATR), the Forward Scattering (FS) and the Photoacoustic Attenuated Total Reflection (PA-ATR). The differences in the resonance coupling halfwidth obtained in the three methods, have been analyzed to account for the different decay processes involved in each spectroscopy. An estimate for the attenuation length of the multiple scattering and directional scattering processes is obtained.
