	Hello,
Thank you for your reply. 
I am using the complex data. However, I have the following problem, when using the setmaterial function:
- My data has three columns: wavelength, real part of the index, and imaginary part of the index
 - setmaterial with the property name "sampled data" only takes 2 or 4 inputs.
 - If I use only two,I don't get the imaginary part, if I take 4, even though I have only 3 in my data set (I set the last column to zero), I get wrong material parameters
 
Thank you for your help and best regrds,
TimÂ
