Dynamic Beam Steering by All-Dielectric Magneto-Optical Nanoantennas

• We propose employing magneto-optic nanoantenna based on split-ring resonator of bismuth-yttrium iron garnets that allows transmitted optical beam steering using externally applied low magnetic field. The proposed magnetic nanoantenna produces a few-degrees spanning of the optical beam propagation direction, controlled by the strength of the external magnetic field. (C) 2020 The Author(s)
