Spontaneous natural optical activity in disordered media
TL;DR: In this article, the authors theoretically demonstrate natural optical activity in disordered ensembles of nonchiral plasmonic resonators and show that the statistical distributions of rotatory power and spatial dichroism are strongly dependent on the scattering mean free path in diffusive random media.

TL;DR: In this article, optical and terahertz non-transverse, non-separable electromagnetic pulses of toroidal topology that are propagating counterparts of the localized toroidal dipoles launched from toroidal emitter metasurfaces excited by conventional laser pulses are observed.

Magneto-optical response in bimetallic metamaterials
Evangelos Atmatzakis,Nikitas Papasimakis,Vassili A. Fedotov,Guillaume Vienne,Guillaume Vienne,Nikolay I. Zheludev,Nikolay I. Zheludev +6 more
TL;DR: In this paper, the authors demonstrate resonant Faraday polarization rotation in plasmonic arrays of bimetallic nano-ring resonators consisting of Au and Ni sections, which allows to optimize the trade-off between the enhancement of magneto-optical effects and plasmic dissipation.
