Frequency dependent refractive index for Thin Dielectric Film BC

Please login with a confirmed email address before reporting spam

Dear All,

I am working on a COMSOL example called Distributed Bragg (Reflector https://www.comsol.com/model/distributed-bragg-reflector-19275)

In this model "Thin Dielectric Film" boundary is used. So how can I add Frequency dependent material properties from an external file into Thin Dielectric film boundary condition?

I have defined my properties via interpolation table and renamed variable called "tio". Under Thin Dielectric Film BC, I recalled my function as "tio(freq)" however I got an error as attached.

What would be wrong?

Thank you in advance, Best regards
