From: Wide angle and narrow-band asymmetric absorption in visible and near-infrared regime through lossy Bragg stacks

Figure 8

For the lossy Bragg stack made from Al-embedded Al2O3 (Al vol% = 70%, 75% and sublayer thickness = 73.5, 70 nm for Sublayers A and B, respectively, refractive index of Al2O3 = 1.76 and period number = 100): (a) real part and imaginary part of the effective complex refractive index for Sublayers A and B; (b) absorption spectra simulated using the TMM; (c) Degree of Asymmetry (DoA) and its dB value [dB = 10lg(DoA)] calculated using the TMM.
