(a) Schematic of the metasurface-based absorber. (d) Physical model of the absorber, where the metasurface is described by its impedance. (b) Ideal impedance and retrieved impedance for the dispersive metasurface. (c, e) Absorption of the broadband (c) and dual narrowband (e) absorbers at different angles of incidence. (f) Schematic of the plasmonic nanocube based absorber. (g) Typical reflectance of a silver (Ag) nanocube. Figures are reproduced from (a)–(c) [114], (d, e) [37], and (f, g) [115].
