Nonlocality-Mediated Generation of Spatiotemporal Optical Vortices in Epsilon-Near-Zero Metamaterials

V. B. Novikov and T. V. Murzina

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate spatiotemporal optical vortices generation by transmission of laser pulses through epsilon-near-zero metamaterial based on metal nanorod array. The heart of proposed approach is phase singularities in transmittance of metamaterial caused by its optical nonlocality.
