Behaviour of SPP waves frequency spectrum for dielectric/metal/dielectric structures
Mathematical Modeling, Vol. 6 (2022), Issue 1, pg(s) 6-8
In this paper, the authors studied the influence of different phenomena and materials properties on the frequency spectrum of the surface plasmon-polariton (SPP) waves behaviour in “dielectric/metal/dielectric” structures. Among them are spatial dispersion, quantization of energy levels, electron-electron interaction (Coulomb correlations) thickness of a metal layer. Established that for atomically thin metal films mentioned effects affect the frequency spectrum significantly. Mentioned that taking into account quantum-sized effects reveals a specific oscillatory picture of the spectrum that repeats one obtained for chemical potential. Proposed model yields results that have a quite good agreement with an experimental data.
