From: All-dielectric metasurface analogue of electromagnetically induced transparency
(a) Diagram of the metasurface. The geometrical parameters are: a1=150 nm, b1=720 nm, rin=110 nm, rout=225 nm, g1=70 nm, g2=80 nm, t=110 nm, p1=750 nm and p2=750 nm. (b) Schematic of interference between the bright- and dark-mode resonators. (c) Simulated transmittance (blue curve), reflectance (red curve) and absorption (green curve) spectra of the metasurface. (d) Oblique scanning electron microscope image of the fabricated metasurface. (e) Enlarged image of a single unit cell. (f) Experimentally measured transmittance, reflectance and absorption spectra of the metasurface.
