Two Wire Transmission line

I am trying to learn how HFSS wave ports work. I want to excite a two wire transmission line with a wave port to see if I get the expected characteristic impedance and fields. I am using a rectangular wave port but I cannot get equal and opposite currents in each wire. Can anyone help? Thank you.

If you desire to have the characteristic impedance, look at Zo. To see the desired fields of a differential line, go to HFSS -> Fields -> Edit sources and modify the excitation to amplitude scaling of 1 for each conductor and a phase difference of 180 deg.

viel spaB! :)
