Fig 1. | Schematic diagram of the temporal evolution process of plasmonic vortices with the same topological charge generated by different couplers. (a-c) Sample 1 introduces only the geometric phase through varying the orientation angles of the slit resonators. (d-f) Sample 2 introduces both geometric phase and propagation phase through varying the radial position of slit-pairs.
