Hi,
I designed the cross section of the plasmonic slot waveguide using wave optics module in comsol. I used mode analysis method and now I am going to calculate the group velocity of my structure. the group velocity can be calculated using dw/dk where w is the angular frequency and k is the wavenumber. the mode analysis method provides both quantity however, they are constant as I defined a single wavelength. therefor, I can not calculate it.
who has any exprience regarding the calculation of group velocity for the waveguides through the Comsol?
can any one know how I can calculate the group velocity for my structure?
Your help will be appreciated.
I don't how you can do this with a single frequency, unrelated to comsol.

the problem is, as you said, the single frequency.
Do you have any suggestion or recommendation to calculate the group velocity of the waveguide I designed.
From the definition I would run one or two more frequencies and use a difference formulation for the derivative
