Surface Plasmon Polaritons Visualized with PiFM

Surface plasmon polaritons (SPP) at the gold-air surface imaged via PiFM. p-polarized 809 nm laser beam is focused via 1.49 NA objective lens with a varying incident angle (controlled via a linear translation stage). Top images show the CCD images of the illumination spot.
