Hi there. I am experiencing exactly the same problem with quite similar system (in my case dielectric grating embedded in metal nn a dielectric substrate). I am wondering if it has been done any progress on this respect, I am using RCWA coupled with Zemax with the dynamic link. Having thousand of ray in Zemax and being forced to use high number of k (hundreads), make the dynamic link unusable becasue of unpratical simulation time.

Thank you for your help
