Figure 3: Dependence of the Q-factor on the array size of the metasurface.
From: All-dielectric metasurface analogue of electromagnetically induced transparency
(a) Vector plot of the magnetic field showing the coherent excitation of the magnetic dipoles within the dark-mode resonators. (b) Scanning electron microscope images of the dielectric metasurface with different array sizes. The inset shows the magnified view of a 20 × 20 array. (c) Transmittance spectra of arrays with different sizes. (d) The extracted Q-factors of the metasurface as a function of array size.
