Change global parameters as the frequency changes

Please login with a confirmed email address before reporting spam

I have a sellmeiers equation to calculate the refractive index of material and is defined in global parameters (initial lambda = 1550 nm)

Eg: n_Si = 1 + (0.00898 lambda^2/1104lambda^2)

lambda = c_const/frequency

As i am performing the frequency domain (range 19145GHz to 19864GHz), the value of n_Si should be changed. I tried using with variable freq but it shows error. Could you please help me with this?

Thanks
