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 dispersion into account, such as the hydrodynamic model. Here, we show that nonlocality in the metallic response affects surface plasmons propagating at the interface between a metal and a dielectric with high permittivity. As a direct consequence, any…

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

It is shown that the polarizability of simple metal particles exhibits above the Mie resonance a collective excitation which is the analogue of the dipolar surface plasmon observed on the flat surfaces of various simple metals.

Modified field enhancement and extinction by plasmonic nanowire dimers due to nonlocal response.

This work numerically implements the hydrodynamical Drude model for arbitrary nanowire geometries, and finds that nonlocal response can strongly affect both the field enhancement in between the dimers and their respective extinction cross sections.

Probing the Ultimate Limits of Plasmonic Enhancement

It is found that the dominant limiting factor is not the resistive loss of the metal, but rather the intrinsic nonlocality of its dielectric response, which has implications for the ultimate performance of nanophotonic systems.

A generalized non-local optical response theory for plasmonic nanostructures.

This theory explains surprisingly well both the frequency shifts and size-dependent damping in individual metallic nanoparticles as well as the observed broadening of the crossover regime from bonding-dipole plasmons to charge-transfer plasmon in metal nanoparticle dimers, thus unravelling a classical broadening mechanism that even dominates the widely anticipated short circuiting by quantum tunnelling.

This work shows that perfect imaging is surprisingly only marginally affected by nonlocal properties of a metal slab, even for a deep subwavelength case and an extremely thin film, and waveguiding of gap plasmons even shows a positive nonlocal influence on the propagation length.
