Where the error is ?

Hello all !

The system of the photo is a plasma generation(by microwaves) champer
The plasma is generated at the Focus2(F2)

The system includes ....
(M) Magnetron : is rapresentated by a discrete port and a cylinder(monopol)
(RW) Rectagular Waveguide
(3ST) 3 Stub Tunner : Tunning element
(WCT) Waveguide to Coaxial Transition
(EC) Ellipsoidal Champer of low pressure
(F) Focus of the elipsoid

The theory says that the ellipsoide concentrade at Focus2(F2) the energy transmited from Focus1(F1)
The probes wich i placed to the Focus2 they are all give zero electric & magnetic fields instead of maximum, WHY ?
Where i do wrong ?

Guys please help me with this , i must finish the simulation and then construct the dum thing .
The clock is tiking and at the end i will be so very f...ed

Thank you
