Fig. 3: Enhancement of the plasmon quality factor by MFPD.

From: Inducing exceptional points, enhancing plasmon quality and creating correlated plasmon states with modulated Floquet parametric driving

Fig. 3

A source at x = 0 induces plasmons propagating along the x-axis. The plasmon amplitude is exponentially damped according to Eq. (19). Blue and green curves show the plasmon wave with MFPD switched on and off, respectively. The enhancement of the plasmon quality factor shows in a larger propagation length and agrees well with the prediction of Eq. (20). A driving strength of h = 0.75hc was used in the simulation.
