Q-factor enhancement of Fano resonance in all-dielectric metasurfaces by modulating meta-atom interactions

Abstract We numerically investigated the effects of meta-atom interactions on the Fano resonance in all-dielectric metasurfaces by introducing alternately flipped asymmetric paired bars (APBs) and split asymmetric paired bars (SAPBs). With alternately flipped configurations, the Q-factor of the Fano...
