Abstract

Image dipole effects are highly dependent on the polarization direction, constructive (destructive) for the vertical (horizontal) dipole with respect to the interface, respectively. Polarization resolved detection of light scattered off a gold nano particle functionalized tip on a flat gold surface enables the study of the image dipole orientation effects on the scattering type near field scanning optical microscope signal. A propagating surface plasmon polariton as an excitation source sufficiently reduced the large background by virtue of its evanescent nature capacitating the quantitative description of the image dipole. At large tip-to-sample distances, the Fabry-Perot like interference between the radiations from the GNP and from the image dipole induced at the flat gold surface, are evident. The horizontal- polarization and vertical-polarization Fabry-Perot oscillations, however, are out-of-phase with each other. As the tip approaches the surface, the vertical component get further enhanced while the horizontal one gets suppresses, demonstrating the polarization reversal of image dipole as predicted by theory.
