The analytical evolution of the out-of-plane SPP field [〖Re(E〗_z)] at the center of the dual vortex coupling structure with geometric charge m=-1, with separation L_sep=1.63λ_spp; the time origin defined when SPPs field is maximum at the center of plasmonic vortex CS. The scale bar represents λ_spp, and the color map is same as in Fig. 2.
