complex reference impedance
Hallo,
embedded transmission lines (microstrip and coplanar waveguides)
in general have complex characteristic impedances Z, due to losses.
Is there any need to express the scattering matrix of such "complex lines"
with complex reference impedances, or can we still use the Touchstone
export file for real reference impedance.
Thanks for any reply.

Or to mention another aspect.
In general voltage sources have complex output impedances. What to do, if we want to connecting it to a device, described by its s-matrix.
Is it possible to normalize each s-matrix in a cascade to an arbitrary real reference impedance without loosing information, even if we have to do with complex in and output impedances.
