Adsorption of a evanescent waves

[maurice74]

The question is:
in a total reflection setup, we have an evanescent waves created in the second medium, under the separation surface. If this medium is highly adsorbing, would then affect the reflected light ?
Let's say the first medium has adsorption zero, while the second is highly adsorbing. Would that change the reflectivity of the surface ?

Yes. Write out the Fresnel Coefficients for the problem. A lossy material has a complex $\epsilon$ or $\mu$
