Extended Data Fig. 3: Transmittance Spectra for w1 and l2 Gradient Metasurfaces.
From: Optical control of resonances in temporally symmetry-broken metasurfaces

(a) Transmittance spectrum for varying w1 (equivalent to Fig. 2h, left) indicated by the blue-to-red color map. The transmittance is offset by 0.1 for clarity. (b) Transmittance spectrum for varying l2 (equivalent to Fig. 2h, right), plotted similarly to (a). The white light used for taking the spectra was polarized along the x-axis of the sample.
