Complex refraction index of a coating

Is there a way to plot/save the complex part of the refraction index of a (multilayer) coating? 

I can find the complex refraction index for a single layer of  a coating in the COATING.DAT, but not for multilayer coatings. Moreover, encrypted coating do not have details on their single layers, so I cannot reconstruct anyway the complex refraction index.

I don’t believe there is. The provided plots show the Reflectivity, Transmission, Absorption and Phase of the coating, but I don't think the effective complex index of the whole stack is presented anywhere. 

You may have more luck with a coatings design program like the Essential Macleod.
