Reply To: Calculate resonator coupling Q from HFSS and Maxwell

Hi Long, 

There are three inductors in your case. You need to add ports on the three one as well. Run the simulation and get the Z-parameter, 
Mutural inductance is Imag(Z12)/omega, L1= Imag(Z11)/omega and L2=Imag(Z22)/omega. The coupling factor = M/sqrt(Z11*Z22).

 

Best regards,

Rong
