Аннотация: We have studied numerically the propagation of surface plasmon polaritons (SPPs) in linear periodic chains of plasmonic nanoparticles of different shapes. The chains are deposited on top of a thick dielectric substrate. While in many commonly considered cases the substrate tends to suppress the SPP propagation, we have found that this adverse effect is practically absent in the case when the nanoparticles have the shape of oblate spheroids with sufficiently small aspect ratio (e.g., nanodisks) whose axes of symmetry coincide with the axis of the chain. © 2016 AIP Publishing LLC.

Аннотация: The interaction of two wave fields of different nature in a disordered medium with an arbitrary relation between the mean value P and rms fluctuation lambda of the coupling parameter is studied. A significant reconstruction of the eigenfrequencies, damping parameters, and susceptibilities of the system occurs when the situation changes from the model of a homogeneous medium (P not equal 0, lambda=0) to the model of the disorder-induced crossing resonance (P=0, lambda not equal 0). The concept of two effective media in the same material, which was introduced for the latter model in earlier work, is extended here to the case P not equal 0. [S0163-1829(99)10313-8].
