From: Plasmonically Enhanced Reflectance of Heat Radiation from Low-Bandgap Semiconductor Microinclusions
Computational methods employed to obtain the optical spectra for the insulator composites with semiconductor microinclusions. (a) Schematic illustrating the Monte Carlo model of propagating photons inside composites with scattering microinclusions for modeling the transport of the incident thermal radiation. An infinitesimally thin beam of incident photons is scattered within the microcomposite until either the photons are absorbed or they exit the system. The randomly distributed small open circles represent microinclusions that serve as scattering and absorption centers for the photons. The decrease in the thickness of the color trajectories in the schematic represents the decrements in the photon weights as they execute random motion in the microcomposite layer. The direction of photon exit from the composite, characterized by the angle α in the Monte Carlo model, varies with each random trajectory and for a large number of photons cumulatively gives rise to diffuse reflectance or transmittance. (b) Work-flow for the computation of the simulation parameters based on Mie theory and MG-EMT for use with the Monte Carlo method.
