Rudenko S. Dimensional effects of linear amplitude anisotropy in surface plasmon resonance

The dissertation is concerned with the investigation of SPR phenomenon by the PM method. New features of linear amplitude anisotropy in the SPR phenomenon, which related to the dimensional effects in the nanosized continuous and cluster gold films, and also gold-dielectric nanocomposite structures, are revealed. A new principle of registration of the SPR phenomenon is offered by measuring of the polarization difference of internal reflection coefficients of linearly polarized radiation. It is revealed, that sign of curvature of angular dependences of this parameter for nanosized films of gold and its nanocomposites shows the different mechanism of resonance excitation of the surface plasmon-polaritons by the electromagnetic radiation. Moreover, the sign of curve slope shows the degree of dominating either s- or р- polarization state. This effect is revealed for the gold films with the different degree of clustering that is represented in the frequency dispersion of characteristic of angle of isotropic reflection s- and р- polarized radiation. The appearance of classical and topological dimensional effects, and also transition between them in the nanosized gold films is shown in the PM presentation.
