We theoretically investigate the propagation of surface plasmon polaritons (SPPs) for the metal-dielectric-metal slot waveguide coupled to a disk cavity filled with gain material. The transmission and reflection characteristics of the resonant structure are numerically analyzed based on coupled-mode theory. The influence of structure parameters on the spectra of transmission is invest... https://www.bekindtopets.com/deal-alert-NHL-Winnipeg-Jets-Distressed-iPhone-13-Pro-Max-MagSafe-Case-p96268-great-save/
