摘要: Excitation and propagation of surface plasmons in silver films structured with narrow straight grooves were visualized unprecedented detail by means near-field optical techniques. Reflectivity, transmissivity, scattering loss the are demonstrated. Their values determined semiquantitatively. The plasmon attenuation found to be dominated material surface/interface imperfections.
