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)?
