Dear Erik,

I checked the code and it does not seem to use both indexes of refraction to calculate the reflectivity. It uses indeed the complex index of the surface to apply the Fowler approach to the calculations.

Apparently the code just checks for the presence of a complex index:

       PropertyPointer =
                aMaterialPropertiesTable->GetProperty("REFLECTIVITY");
       PropertyPointer1 =
                aMaterialPropertiesTable->GetProperty("REALRINDEX");
       PropertyPointer2 =
                aMaterialPropertiesTable->GetProperty("IMAGINARYRINDEX");

       iTE = 1;
       TM = 1;

       if (PropertyPointer) {

               theReflectivity =
               PropertyPointer->Value(thePhotonMomentum);

       } else if (PropertyPointer1 && PropertyPointer2) {

               CalculateReflectivity();
       }

And before the call to DielectricDielectric(), calculates the reflectivity via the line

       theReflectivity =
             GetReflectivity(E1_perp, E1_parl, incidentangle,
                             RealRindex, ImaginaryRindex);

This seems to apply also for the DielectricMetal() case. Maybe I am missing something?

thank you, Nicolas
