Is there any way to directly add index of refraction to a material?

Hello, I am trying to create a blank material with a specific index of refraction. I have looked through the "add properties option" and I cannot find an index of refraction.

I have been able to find the Relative permeability and Relative permittivity under the baisic tab but I would like to add index of refraction directly to a material.

I can see real index of refraction as a property of air and I can edit it's values to have the value of silica aerogel of 1.03.

For reference I am trying to duplicate the work done here http://lhcb-doc.web.cern.ch/lhcb-doc/presentations/conferencetalks/postscript/2007presentations/T.Bellunato.pdf

Hello Owen,

  • Right-click on the Material 1 (or whatever you may have renamed it) node in the Materials branch of the Model Builder,
  • In the Settings window, in the Materials Properties tab, expand Electromagnetic Models
  • There you'll find Refractive index, real part (n)

Best,

Jeff
