E or E1 or E2 in my plasma model

Hello,

I am trying since some days now to "copy" the microwave heated 2D model to a different geometry.
My geometry is axial-symmetric in real.
But I first started it in 2D only, but since I am not able to handle the EM fields right on 2D (I want a coaxial Power input of microwave) , I gave up this 2D to go to the 2D axial-symmetry. At least there I can have the coax input right away.
(But there I have a problem with the S-parameters.. it plots me Fourrier Coefficients?) (2Daxisym-EM)

Now implementing the plasma is not that easy.. in my model I may have deleted and put back the EM node..
So I have a E2 field variable..
But it does not look consistent with the port equation descriptions?
(2Daxisym-Argon)

Where do I do my errors?

If someone has an expert eye on it, that would be very helpful.

Thanks
Lukas
