Roadmap on Nonlocality in Photonic Materials and Metamaterials
Francesco Monticone, N. Asger Mortensen, Antonio I. Fernández-Domínguez +63
Photonic technologies continue to drive the quest for new optical materials with unprecedented responses. A major frontier in this field is the exploration of nonlocal (spatially d…
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…
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…
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…
Broadband Tunable THz Absorption with Singular Graphene Metasurfaces
Emanuele Galiffi, John Pendry, Paloma Arroyo Huidobro
By exploiting singular spatial modulations of the graphene conductivity, we design a broadband, tunable THz absorber whose efficiency approaches the theoretical upper bound for a w…
