(a) Surface topography of rough silver surface.
(b) Distribution of the surface plazmon near-field on rough
silver surface.
(c) Vector diagram of plasmon scattering
(d) FFT of the near-field image
The point on the FFT image corresponds to scattering maximum arises from the backscattering enhancement effect (for details see article "Konopsky V.N., Kouyanov K.E., Novikova N.N. Investigations of the interference of surface plasmons on rough silver surface by scanning plasmon near-field microscope. Ultramicroscopy, 2001, V.88, P.127-138")
