A nanometal is a nanometric metallic structure. A plasmon is a collective excitation of an electron gas. A plasmon polariton is a plasmon coupled to an electromagnetic wave. Whereas plasmons in bulk metal do not couple to light fields, a thin metal film can sustain surface polaritons when excited by light. This can be achieved via an evanescent prism coupling, the help of surface corrugations to ensure momentum matching, etc. Such surface polaritons propagate as coherent electron oscillations parallel to the metal surface and decay exponentially perpendicular to it. Thus, the electromagnetic energy is confined to dimensions below the diffraction limit perpendicular to the metal surface.

期刊介绍:
Surface Science Reports is a journal that specializes in invited review papers on experimental and theoretical studies in the physics, chemistry, and pioneering applications of surfaces, interfaces, and nanostructures. The topics covered in the journal aim to contribute to a better understanding of the fundamental phenomena that occur on surfaces and interfaces, as well as the application of this knowledge to the development of materials, processes, and devices. In this journal, the term "surfaces" encompasses all interfaces between solids, liquids, polymers, biomaterials, nanostructures, soft matter, gases, and vacuum. Additionally, the journal includes reviews of experimental techniques and methods used to characterize surfaces and surface processes, such as those based on the interactions of photons, electrons, and ions with surfaces.
