Shape Memory Photonic Metamaterial [PDF]

open access: yesConference on Lasers and Electro-Optics, 2016
We report the first reconfigurable metamaterial based on the shape memory alloy. In the heating cycle structural elements of this metamaterials exhibit a hysteresis-type shape transformation that leads to non-volatile switching of its plasmonic properties.

Photonic magnetic metamaterial basics [PDF]

open access: yesPhotonics and Nanostructures - Fundamentals and Applications, 2011
In the present study, we provide a detailed analysis for the study of photonic metamaterials. We demonstrate the polarization and orientation dependent transmission response of split ring resonators at the infrared and visible band. We provided optical measurements only for one case, in which electric component of the incident field was coupled to ...

Graphene in a photonic metamaterial

open access: yesOptics Express, 2010
We demonstrate a photonic metamaterial that shows extraordinary sensitivity to the presence of a single atomic layer of graphene on its surface. Metamaterial's optical transmission increases multi-fold at the resonance frequency linked to the Fano-type plasmonic mode supported by the periodic metallic nanostructure.

Holographic free-electron light source

open access: yesNature Communications, 2016
Controlling the generation of light in nano-scale systems is a challenging task and is of growing importance. Here, Li et al. propose a means of controlling the wavefront of light emanating from a single nano scale emitter by holographic principles using

Electro-mechanical light modulator based on controlling the interaction of light with a metasurface

open access: yesScientific Reports, 2017
We demonstrate a reflective light modulator, a dynamic Salisbury screen where modulation of light is achieved by moving a thin metamaterial absorber to control its interaction with the standing wave formed by the incident wave and its reflection on a ...

Topological characteristic of Weyl degeneracies in a reciprocal chiral metamaterials system

open access: yesNew Journal of Physics, 2021
Being a research hotspot in the field of topological semimetals, Weyl points (WPs) are monopoles of Berry curvature in momentum space. In this paper, we report the existence of photonic Weyl degeneracies in a reciprocal chiral metamaterials system.
