Journal ArticleDOI
Surface plasmons and nonlocality: a simple model.
TL;DR: A local analogue model is presented and it is shown that spatial nonlocality can be represented by replacing the nonlocal metal with a composite material, comprising a thin dielectric layer on top of a local metal.
Journal ArticleDOI
Transformation-optics description of nonlocal effects in plasmonic nanostructures
Antonio I. Fernández-Domínguez,Aeneas Wiener,Francisco J. Garcia-Vidal,Stefan A. Maier,John B. Pendry +4 more
TL;DR: An insightful transformation-optics approach is developed to investigate the impact that nonlocality has on the optical properties of plasmonic nanostructures and elucidate the optimum size that maximizes its absorption and field enhancement capabilities.
Journal ArticleDOI
Nonlocal effects in the nanofocusing performance of plasmonic tips.
Aeneas Wiener,Antonio I. Fernández-Domínguez,Andrew P. Horsfield,John B. Pendry,Stefan A. Maier +4 more
TL;DR: It is shown that, although spatial dispersion reduces the field enhancement taking place at the structure apex, it also diminishes the impact that geometric imperfections have on its performance.
Journal ArticleDOI
Rapid ultrasensitive single particle surface-enhanced Raman spectroscopy using metallic nanopores.
Michael P. Cecchini,Aeneas Wiener,Vladimir A. Turek,Hyangh Chon,Sangyeop Lee,Aleksandar P. Ivanov,David W. McComb,Jaebum Choo,Tim Albrecht,Stefan A. Maier,Joshua B. Edel +10 more
TL;DR: It is shown that the full vibrational spectrum of the analyte can be detected with ultrahigh spectral sensitivity and a rapid temporal resolution of 880 μs, improving on current nanopore-based electrical and optical detection techniques.
Journal ArticleDOI
Electron-Energy Loss Study of Nonlocal Effects in Connected Plasmonic Nanoprisms
Aeneas Wiener,Huigao Duan,Huigao Duan,Michel Bosman,Andrew P. Horsfield,John B. Pendry,Joel K. W. Yang,Stefan A. Maier,Antonio I. Fernández-Domínguez +8 more
TL;DR: A full three-dimensional nonlocal hydrodynamic solution of Maxwell's equations in frequency domain that implements the electron beam as a line current source is developed and used to investigate the emergence of nonlocal effects in plasmonic nanostructures.
