+ | == Roughness Models == | ||
+ | |||
+ | The roughness model assumes a continuous transition (error function) of the optical constants between two layers and can be altered by the roughness parameter σ. | ||
+ | |||
+ | Two modes implemented to calculate the spectra. | ||

+ | == Adaptive Layer Segmentation Model == | ||
+ | |||
+ | The slicing parameters can be changed in the " | ||
+ | |||
+ | The default model is " | ||
+ | The global model is described in the diploma thesis of M. Harlander. | ||
+ | |||
+ | If the thickness is smaller than σ both models describe the interface almost like the roughness approximation by Nevot& | ||
+ | However there are differences for the case σ> | ||
+ | The global models should give you physical more feasible results which cannot be modelled by the analytical approximation. | ||
