Metasurfaces-Based Absorption and Reflection Control: Perfect Absorbers and Reflectors

Figure 2

(a) Calculated incidence-angle dependence of absorption by a layer of 500 nm close packed silica filled inclusions buried in gold. (b) Under the same conditions as (a), there is azimuthal dependence of absorption for 20° off-normal incidence [3].
