Anisotropic excitation of surface plasmon polaritons on a metal film by a scattering-type scanning near-field microscope with a non-rotationally-symmetric probe tip

We investigated the excitation of surface plasmon polaritons on gold films with the metallized probe tip of a scattering-type scanning near-field optical microscope (s-SNOM).The emission of the polaritons from the tip, illuminated by near-infrared laser radiation, was found to Exhaust Tips be anisotropic and not circularly symmetric as expected on
