For LCP light, the SPP focuses generated by the left semicircle slit (a) and the right semicircle slit (b) shift downward and upward, respectively. For RCP light c and d, the positions of the SPP focuses are reversed. e, f The SPP focuses generated by spin-independent plasmonic lens are all in center for LCP and RCP light. g, h The transversal and longitudinal distributions of the SPP focuses
