TL;DR: In this article, the experimental observation of near-field optical effects close to Au nanoparticles using a photon scanning tunneling microscope (PSTM) allowed an unprecedented direct comparison with theoretical computations of the optical near field intensity.

TL;DR: In this paper, a back-side slit-illumination method that incorporates a periodic array of grooves carved into the front side of a thick metal film was proposed to enhance the propagation of SPPs away from the array, enabling them to be unidirectionally launched from, and focused to, a localized point.

TL;DR: In this paper, surface plasmons are realized by a prism coupling arrangement involving an opaque aluminum screen for a distinct separation of excitation and propagation region, and the surface plasmon propagation length as a function of film widths is measured by detecting stray light due to surface plasar scattering with a conventional optical microscope.

TL;DR: In this paper, a photon scanning tunneling microscope was used to probe the field of surface plasmon polariton modes excited on finite-width thin metal films (metal stripes).

TL;DR: In this article, the authors used the Green dyadic technique to study the propagation of a local excitation along metallic nanowires of a subwavelength cross section, and analyzed the properties of the electromagnetic eigenmodes of the nanwires in terms of the local density of states.
