Planar, disordered assemblies of small particles incorporated in layered media -- sometimes called ``disordered metasurfaces'' in the recent literature -- are becoming widespread in optics and photonics. Their ability to scatter light with exotic ang

Ce manuscrit s’intéresse principalement à l'influence de la répulsion entre électrons libres sur la réponse optique des métaux. Les modèles de matériaux classiques considèrent que la réponse d'un métal est locale -- c'est à dire que la

The group velocity of a plasmonic guided mode can be written as the ratio of the flux of the Poynting to the integral of the energy density along the profile of the mode. This theorem, linking the way energy propagates in metals to the properties of

Recent experiments have shown that spatial dispersion may have a conspicuous impact on the response of plasmonic structures. This suggests that in some cases the Drude model should be replaced by more advanced descriptions that take spatial dispersio

Recent experiments with film-coupled nanoparticles suggest that the impact of spatial dispersion is enhanced in plasmonic structures where high wavevector guided modes are excited. More advanced descriptions of the optical response of metals than Dru

The repulsion between free electrons inside a metal makes its optical response spatially dispersive, so that it is not described by Drude's model but by a hydrodynamic model. We give here fully analytic results for a metallic slab in this framework,

This manuscript is mainly focused on the influence of repulsion between free electrons on the optical response of metals. Classical material models consider that the metallic response is local -- i.e. that the response at a given point only depends o
