In this paper, surface plasmon polaritions (SPPs) induced by a tightly focused and radially polarized vortex beam on a planar metal/dielectric interface is simulated and the properties of the SPPs self-interference are studied. It is shown that utilizing vortex beam can avoid the influence of the central zero-order angular spectrum. Besides, the impacts of various factors as different topological charge, substrates parameters and metallic film material on the generation of SPPs interference pattern are compared and analyzed.
