Optically-Induced Antiferromagnetic Order in Mie-Resonant Dielectric Metasurfaces

摘要

We study silicon-based metasurfaces with complex unit cells composed of Mie-resonant dielectric nanodisks and nanorings and observe experimentally a signature of optical response with a staggered structure of optically-induced magnetic dipole moments, associated with the so-called optical antiferromagnetic order.
