Temperature dependent refractive index of iron (Fe)

      Hi all,

      I want to know the temperature dependent refractive index (also called thermo-optic coefficient) of iron (Fe) or stainless steel, but I can't find it in Edupack. Can you help me out?

      I think it is in the FDTD and MODE material database but I am not sure, and I don't have access to these modules through my university.

      Cheers!

      Unfortunately, FDTD and MODE material database do not have any thermal data. and they cannot directly simulate the thermal change, even you have the  thermo-optic coefficient. What they simulate is the actual refractive index either from the material database, or perturbation simulated from HEAT. Please refer

      If you need, you will have to search literature to get the  thermo-optic coefficient.
