Theoretical description of visualization of nanoobject with surface plasmon polariton scattering

The theoretical aspects of visualization of nano-objects by scattering of surface plasmon-polariton are discussed in the frame of local-field approach. It was shown that the image intensity measured by the optical detector depends on the distance between nano-object and surface and their interaction is resonant. Besides, it was shown that the main feature of the used approach is taken into account the inhomogeneity of the local field at the nanoparticle. In part, it was obtained that position of maximum intensity depends linear on particle radius. The results of calculations were compared with experimental data obtained by other scientific teams.
