Data files and Matlab codes for analyzing a multilayer thin-film photonic radiative cooler

When optical beam hits a multilayered system of different refractive indices, it gets reflected, refracted, and absorbed in a way that can be derived from the Fresnel equations. But, with increasing number of layers, math becomes complicated. We have designed a MATLAB algorithm underlying the transfer-matrix method for the calculation of the optical properties of multilayered system and have verified it with experimental observations.
