Hi Mick,
The Z matrix is always meaningful.
[V] =3D |Z|[I]
As it implies, it is a simple ratio of voltage to current.
Hence, the mixed mode coupling shows when you have a differential =
voltage for instance, how much even mode current do you get.
Thanx,
Bill
P.S. As my friend Eric Bogatin always told me 'It's all in the matrix'. =
:-)
