Topology of plasmon-polariton vortices on an adaptive mirror

Nonlinear plasmonic switching in graphene-based stub nanoresonator loaded with core-shell nanowire

“…In the linear regime for cascade scheme with ∆ = 0 the polarization Re (ρ 32 ) does not achieve the necessary value against the background of large losses, see Fig. The representation (6) for the polarization change rate allows us to understand the contribution of each linear (and nonlinear [62,63]) effects to the process of switching and achieving the stationary regime of SPP-QD interaction in the stub. In particular, the initial deviations for polarizations from the stationary values given by ρ 21(32) (0) = 1.01 ρ21 (32) were used for simulation in Fig.…”

Formation of Surface Plasmon-Polariton Vortices at Reflection from Curvilinear Boundary

“…SPPs from the inhomogeneity of permittivity with curvilinear boundary [35][36][37]. The plasmon vortices do not arise in case of superposition of the modes reflected from a straight line boundary of the inhomogeneity.…”
