This paper describes the first direct observation of surface plasmon propagation on a metallic thin film deposited on a glass slide, thus facilitating the first direct measurement of the propagation length. This was achieved using photon scanning tunneling microscopy (PSTM). Subsequently, near-field observations of the surface plasmon buried at the metal-glass interface, generated from a discontinuity in the metallic thin film, were reported.
