“…Especially interesting manifestations of the specific DC-distribution details predicted in this paper can be expected in combination with the external or SPP-induced static fields, for example, the SPP-induced magnetization [20][21][22][23]. In particular, the nanoscale variations of the energy and momentum distributions may influence the spin transport processes [41][42][43], induce additional features of the light-matter interaction in presence of high-gradient local optical fields [44], etc.…”

“…An especially important fact is that the transverse electric field E x vanishes at a certain point x e near the interface (see Fig. 3b; under the conditions ( 42), (43), x e = -0.21 nm). This fact induces additional peculiar features in the spatial behavior of various field characteristics, as will be shown below (see Figs.…”

Our subject is an electromagnetic field near the plane interface dividing a conductive and a dielectric media, under conditions supporting the surface plasmon-polariton (SPP) propagation. The conductive medium is described by the hydrodynamic electron-gas model which enables a consistent analysis of the field-induced variations of the electron density and velocity at the interface and its nearest vicinity. The distributions of electromagnetic dynamical characteristics: energy, energy flow, spin and momentum are calculated analytically and illustrated numerically, employing the silver-vacuum interface as an example. A set of the "field" and material contributions to the energy, spin and momentum are explicitly identified in respect to their physical origins, and the orbital (canonical) and spin (Belinfante) momentum constituents are separately examined. In this context, a procedure for the spin-orbital momentum decomposition in presence of free charges is proposed and substantiated. The microscopic results agree with the known phenomenological data but additionally show specific nanoscale structures in the near-interface behavior of the SPP energy and momentum which can be deliberately created, controlled and used in nanotechnology applications.
