(a) Schematic of the metasurface absorber made out of silicon grating. (b) Calculated diffraction efficiency of a grating. (c) Fabricated sample. (d) Measured absorption coefficients. (e) Fabricated sample of a complex silicon grating. (f) Measured transmission and reflection coefficients with and without pattern. Figures are reproduced from (a, b) [117], (c, d) [118], and (e, f) [104].
