Multiconductor Transmission Line

Please login with a confirmed email address before reporting spam

Hello everibody,

I have a problem to calculate the parameters of a multiconductor transmission line.

I designed the cross section in 2D on the xy plane.
To model for transversal admittance matrix using the postprocess "rlcmatrix" no problem (I follow the example "microstip" in the model library).
Now I have to calculate the longitudinal impedance matrix. I need to inject a current into the conductor in z-direction and this current must return in the "ground" conductor.
I tried to change the port options in the model for calculating the capacity, but it doesn't works because the results are patently wrong.
How can I do?

Thank you for your answer and for you suggest!

Alberto
