Hello. I am a new user of comsol multiphysics and I kindly want someone to help me concerning the below problem:
I am trying to create a new(user defined ) material based on generated complex permittivity using Comsol 4.4. the data are arranged like this: f=(1,2,3,4) n=(0,5,10,15) k=(1,2,3,4). Where f, n, and k are the frequency, real part of refractive index and imaginary part of refractive index, respectively.
how can I put those material properties in COMSOL ?
Thank you

4.4 was a long time ago.
Either you will need to enter a complex relative permittivity or a conductivity. Try complex permittivity first.
Look up the transformation from n,k to e', e'' in a textbook.
