Refractive index sensor based on fano-magnetic toroidal quadrupole resonance enabled by bound state in the continuum in all-dielectric metasurface

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Feb. 19, 2024

Abstract For the first time, an all-dielectric metasurface ultra-sensitive refractive index (RI) sensor with very high quality factor (QF) and figure of merit (FOM), Fano-magnetic toroidal quadrupole (MTQ) resonance enabled by bound state in continuum (BIC) terahertz (THz) region was designed. Furthermore, MTQ THz due to a distortion symmetry-protected states designed structure investigated. Also, achieve dark mode, combination three methods including (i) breaking symmetry, (ii) design complex structures, (iii) changing incident angle utilized. The broken symmetry caused new mode be excited, which is suitable for sensing applications. able sense wide range RI resonance, where its properties were improved value sensitivity (S) from 217 GHz/RIU 625 GHz/RIU, FOM 197 RIU –1 2.21 × 10 6 QF 872 5.7 .
