TLDR
In this article, a zero-index metamaterial formed by stacked silicon rod unit cells is proposed to realize all-dielectric impedance-matched zero index metammaterials operating at optical frequencies.Abstract:
Previously demonstrated zero- or negative-refractive-index metamaterials at optical frequencies suffer from large ohmic losses because of the need to use metals. Metamaterials formed by stacked silicon rod unit cells allow the realization of all-dielectric impedance-matched zero-index metamaterials operating at optical frequencies, potentially benefiting the development of angular-selective optical devices.read more

Dielectric Meta-Reflectarray for Broadband Linear Polarization Conversion and Optical Vortex Generation
TL;DR: This work presents an alternative approach to plasmonic metasurfaces by replacing the metallic resonators with high-refractive-index silicon cut-wires in combination with a silver ground plane, and demonstrates optical vortex beam generation using a meta-reflectarray with an azimuthally varied phase profile.
