From: Disordered photonics behavior from terahertz to ultraviolet of a three-dimensional graphene network
a Detection geometry of the goniophotometric data. θ is the horizontal scattering angle and Φ the vertical one. Due to the cylindrical symmetry (θ=Φ), only the horizontal angle (θ) has been scanned with a sensitivity of 0.1°. b Incident and transmitted intensities of S1 sample at different θ angles for the 780 nm (blue and red stars) and 7 μm (light blue and yellow diamonds) wavelengths. c Integrated transmittance T(θ,λ) for the S1 sample as a function of the scattering angle θ, as computed from Eq. 1 for 780 nm (light blue squares) and 7 μm (violet squares) wavelengths, respectively. T(θ,λ) values converge rapidly to the transmittance as measured in Fig. 2, supporting the idea that scattering is the key process in the light-3D Graphene interaction. d Fraction of scattered light for the S1 sample for both 780 nm (light blue squares) and 7 μm (violet squares) wavelengths, as computed from Eq. 2.
