Impedance calculation without reference to plane data?

Hello everybody,

 

i have a question/problem with the right impedance of a Trace/DiffPair.

Impedance_FieldSolver.jpg

The Field Solver dialog shows a picture with the magnetic field to the neighbour layers of the highlighted trace segment.

 

 

But on  the yellow Plane Layer 2 isn´t a valid plane data, the plane in this region is free from any copper:

- cutout picture of the yellow plane layer

 

 

So the FieldSolver and the whole impedance calculation isn´t right at all, I think?!

Or is there an option to include a check to referenced plane datas?

 

Thanks,

 

Best wishes,
