How to use sellmeier to creat a material?
is this material for MODE Solutions or FDTD Solutions?
if it is for MODE, you can create the material data and import it into the material database. Please refer this post.
If it is for FDTD, then some care must be taken: this Sellmeier model has no imaginary part. If its absorption (kappa value) is very small, say less than 1e-5 in the interested waveband, then you can import it as before. However, if it has larger absorption, and you omit it, the resulting material fitting will be not accurate, which may lead to wrong result.
Hope this helps.
