Wood Anomalies and Surface-Wave Excitation with a Time-Grating
Emanuele Galiffi, Yao-Ting Wang, Zhen Lim +3
In order to confine waves beyond the diffraction limit, advances in fabrication techniques have enabled subwavelength structuring of matter, achieving near-field control of light a…
Nonlocal effects in plasmonic metasurfaces with almost touching surfaces
Fan Yang, Emanuele Galiffi, Paloma Arroyo Huidobro +1
Geometrical singularities in plasmonic metasurfaces have recently been proposed for the enhancement of light-matter interactions, owing to their broadband light-harvesting properti…
Plasmon Localization Assisted by Conformal Symmetry
Lizhen Lu, Emanuele Galiffi, Kun Ding +3
Plasmonic systems have attracted remarkable interest due to their application to the subwavelength confinement of light and the associated enhancement of light-matter interactions.…
Probing Graphene's Nonlocality with Singular Metasurfaces
E. Galiffi, P. A. Huidobro, P. A. D. Gonçalves +2
Singular graphene metasurfaces, conductivity gratings realized by periodically suppressing the local doping level of a graphene sheet, have recently been proposed to efficiently ha…
Fresnel drag in space-time modulated metamaterials
P. A. Huidobro, E. Galiffi, S. Guenneau +2
A moving medium drags light along with it as measured by Fizeau and explained by Einstein's theory of special relativity. Here we show that the same effect can be obtained in a sit…
Broadband Nonreciprocal Amplification in Luminal Metamaterials
E. Galiffi, P. A. Huidobro, J. B. Pendry
Time has emerged as a new degree of freedom for metamaterials, promising new pathways in wave control. However, electromagnetism suffers from limitations in the modulation speed of…
