Odd mode and even mode impedances

Question asked by ASWIN on Mar 16, 2006

I am simulating a coupled line in momentum and I dont know how to compute the even mode and odd mode impedances.
The structure consists of a simple pair of coupled lines.
For the even mode impedance computation, I set up the ports on each side as common mode ports with 50 ohms impedance and the association is the port below/above it.
I looked at the input impedance and the answer is far off from the required answer.
Same situation with odd mode using differential ports.
Please help me.
