(a) Reflectance spectra of the silicon substrate with and without AR subwavelength structures under normal incidence. (b) Reflectance for s-polarized (black curve with solid square symbols) and p-polarized (red curve with solid dot symbols) incident beam over the angle of incidence (AOI) from 10° to 60°.
