(a) Artistic rendering of the bi-layered hybrid metasurface. (b) Unit cell structure of the proposed structure. The period, thickness, and width of the nanograting are 125 nm, 40 nm, and 120 nm, respectively. (c) The unit cell structure on the y-z plane. (d) Independent control of the spectral intensity and wavelength. The intensity and wavelength of the transmitted light can be controlled by the rotated angle (θ) and size (w, l) of the nanorods, respectively.
