Hello , I have simulated a basic two situations.
The first is straight differential line.
The second is curved differential line.
The excutation is differential + - on the lines so the S2p is differento modes.
in the curved pair line we have a situation where one line is longer then the other.

Two questions:
1.the S2p is differential mode excitation.
how can i investigate the idial straight line and the curved line touchstone files and see the difference

Two questions:
1. what is the proper way to investigate the idial and curved lines touchstone files given the differential excitation and see the missalaighnment.
2. is there a manual I could use to fix the missallighment in the curved differential line.
Thanks.
