Schematic of the problem geometry. A stack of three laterally infinite layers is illuminated by a collimated beam with angle cosines of \(\mu _1\) and \(\mu _0\) outside and inside of the stack, respectively. On the top and bottom surface, Fresnel reflections must be accounted for, while the radiance is continuous at the layer interfaces.
