Richard,

If it doesn't come through on an initial read, I have tried to deconstruct
the fig a) / Fig 1 configuration, and then synthesise it with another
structure with and without the common mode current path, and observe the
effect on current distribution... then compare that with the TL
representation.

If the development isn't clear, I have some more work to do!

I will have to revisit the comments in this thread and tie them to the
cogent points of your page.

Constructive comments are always welcome, and appreciated.

Thanks
Owen
