- Abstract
The amplitudes of the reflected cross-polarized light of C2, C3, and C5 meta-atoms with different orientations are illustrated in Figure 1G-I, which exceed ~0.89, ~0.91, and ~0.75 at the central wavelength of 10.6 m (the working wavelength of the CO SB 2 sb laser), respectively. By arranging the chiral C5 meta-atoms from 0 to 36°, another hologram is obtained and its SEM images are shown in Figure 4D (the SEM images of the sample with a tilt angle are shown in Supplementary figure S4).
