Abstract

We propose high-index truncated cone silicon metasurfaces based mainly on magnetic Mie resonances. From numerical simulation, the intensity of the reflection peak reaches almost 90%, and the full width at half-maximum (FWHM) of the reflectance spectrum is 43 nm. Specific colors covering the entire visible spectrum with saturation close to 1 are available by selecting appropriate geometric dimensions and period of the structure. In summary, the structural colors achieved by the proposed metasurfaces are superior to previous research in comprehensive aspects of reflection peak, the FWHM of the reflectance spectrum, and the saturation of the color. Furthermore, the proposed structure works with a low aspect ratio of 0.46, which largely relieves the difficulty of process manufacturing.
