Help with Waveports
I have run into a problem in my simulations.
I want to simulate the near-field coupling between two adjacent twin-lead lines. To do this, I run two sets of parallel copper lines inside a single vacuum box.
Now I want to define ports, which are defined between each pair of wires on each side of the vacuum box. The problem is that I can only define one waveport per face of the vacuum box, and I need two ports on each side because their are two wires.
Worse still, the waveports can't descriminate between the two sets of wires. If I place the lines far apart so that one wire can't excite the other, and I excite a single wire with port 1, and locate port 2 on the second wire on the opposite end of the box, the simulation will still give me a 100% power transfer for S(1,2).
I have thought about using lumped ports instead, but I don't know the impedance of the transmission lines, and I want to lumped ports to be impedance matched to the lines.
Can anyone help set the ports properly for this simulation? Thanks in advance.
