(A) Calculated and measured transmission and reflection spectra for the three fabricated devices shows RGB in transmission and CMY in reflection mode. The CIE 1931 further provides the coordinates of the produced results [12]. (B) Calculated and measured spectra along with the camera images of broadband visible and near-infrared absorbers implemented with planar nanolayered stacks. Reproduced with permission of [42].
