Hi everyone,

I am trying to extract the inductance and resistance of a coil using HFSS and Maxwell (Eddy Current)
For the HFSS simulation:
I used one lumped port excitation, a radiation boundary and ran the simulation at 13.56MHz. Then , I calculated "L" and "R":
L=Im(Z(1,1))/(2*pi*freq)=2.12uH
R=Re(Z(1,1))=2.31 ohm

For the MAXWELL (Eddy Current) simulation:
I set the analysis setup frequency at 13.56MHz, and I did not use radiation boundary, but I used a current excitation of 1mA. For the calculation of "L" and "R," I used the assign matrix option:
L=1.26 uH
R=0.703 ohm

   

 

 

My first question is why is there a mismatch  in the inductance(L) value and  resistance values (R)?

My second questions is that I am suspicous if MAXWELL(Eddy Current) simulation gives me Rac (AC resistance)?
