Figure 2: Dependence of the Q-factor on the bright- and dark-mode resonator spacing.
From: All-dielectric metasurface analogue of electromagnetically induced transparency
(a) Schematic showing the coupling of the bright-mode resonator to the neighbouring dark-mode resonator. Here, we schematically provide the fields arising due to the bright-mode resonance. (b) Simulated magnetic and electric field amplitudes as a function of resonator spacing. (c) Transmittance curve for the metasurface with varying values of g1 obtained through finite-element frequency-domain simulation. Δ=g2−g1 is used to track the difference in spacing between the bright-mode resonator and the adjacent dark-mode resonators. (d) The extracted Q-factors of the EIT resonance as a function of Δ.
