Chirality metasurface
WebHere, we demonstrate switching of the extrinsic chirality by applied magnetic fields in a magnetoplasmonic metasurface device based on a magneto-optical oxide material, Ce 1 Y 2 Fe 5 O 12 (Ce:YIG). Due to the low optical loss and strong magneto-optical effect of Ce:YIG, we experimentally demonstrated giant and continuous far-field circular ... WebJan 29, 2024 · In particular, the chiral metasurface supports two chiral quasi-BIC resonances, which exhibit distinguished different properties. For example, the Q-factor of “mode 1” (Q ≈ 938.2) is more than an order of magnitude higher than that …
