Cooperative field localization and excitation eigenmodes in disordered metamaterials
Nikitas Papasimakis, Stewart D. Jenkins, Salvatore Savo +2
We investigate numerically and experimentally the near-field response of disordered arrays comprising asymmetrically split ring resonators that exhibit strong cooperative response.…
Strong radiative interactions and subradiance in disordered metamaterials
Stewart D. Jenkins, Nikitas Papasimakis, Salvatore Savo +2
We provide detailed comparisons between experimental findings and numerical simulations of large cooperatively interacting, spatially disordered metamaterial arrays, consisting of…
Many-body subradiant excitations in metamaterial arrays: Experiment and theory
Stewart D. Jenkins, Janne Ruostekoski, Nikitas Papasimakis +2
Subradiant excitations, originally predicted by Dicke, have posed a long-standing challenge in physics owing to their weak radiative coupling to environment. Here we engineer massi…
Reconfigurable anisotropy and functional transformations with VO-based metamaterial electric circuits
Salvatore Savo, You Zhou, Giuseppe Castaldi +4
We demonstrate an innovative multifunctional artificial material that combines exotic metamaterial properties and the environmentally responsive nature of phase change media. The t…
Localization of Electromagnetic Fields in Disordered Fano Metamaterials
Salvatore Savo, Nikitas Papasimakis, Nikolay I. Zheludev
We present the first study of disorder in planar metamaterials consisting of strongly interacting metamolecules, where coupled electric dipole and magnetic dipole modes give rise t…
Superlensing properties of one-dimensional dielectric photonic crystals
Salvatore Savo, Emiliano Di Gennaro, Antonello Andreone
We present the experimental observation of the superlensing effect in a slab of a one-dimensional photonic crystal made of tilted dielectric elements. We show that this flat lens c…
