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 be anisotropic and not circularly symmetric as expected on the basis of literature data. https://pyrodresoners.shop/product-category/hardware-and-bling/
