WavePort.We stick with using the unconjugated value for reference impedance, but now we switch our default approach for extracting S parameters to the pseudo-wave formulation.
Also includes a fix for calculating voltage from current + flux as well as calculating current from voltage + flux, when modes are lossy.
We are still missing proper calculation of mode amps using the non conjugated version of the dot product for lossy modes.Completed

Greptile Summary
Improved handling of lossy modes in WavePort by updating reference impedance calculations and fixing voltage/current computations for transmission line modes.
