    Finding Z21 using HFSS

    I am trying to find the Z21 in HFSS for a modal of interdigital Capacitor which i have simulated. Can anyone tell me about Z21, Z12 parameter. Is it normalized to 50 ohm or not which HFSS is giving me? HFSS giving me img (Z21) = 63.154.
    Please someone guide me. Thanks

    If you know S-Parameters, you can transform them into Z-Parameters by using well known equations.

    C(Farad)=1/{2*PI*Imag[(z11*z22-z12*z21)/z21]}

    Thank you so much. You did a great help for me.
    Can i please get the reference for this formula of C(Farad) ?? I will be grateful.

    Re: Finding Z21 using HFSS

    Dear Sir,

    Can you please tell me the corresponding reference/link to this formula;

    C(Farad)=1/{2*PI*Imag[(z11*z22-z12*z21)/z21]} ??

    Please share it with me because i also have to mention the reference while explaining it. I will be grateful to you.
    Thanks
