Finding inductance and capacitance using S,Y,Z parameters in HFSS

    • Sneh Patel


      I have this 2 coil spiral inductor design (2 lumped ports in Terminal Network) for which I want to find the self-inductance, mutual inductance, and parasitic capacitance. I used the following formula to calculate the inductance. However, I am getting mixed results for different formulas I have tried. I would appreciate your help to see how I can find the accurate parameters of the 2 coil structure.

      1) L = -1 / (2*pi*F*im(Y11))

      2) L = im(Z11) / (2*pi*F)


      Thank you,

      HFSS™ uses a numerical technique called the Finite Element Method (FEM). This is a procedure where a structure is subdivided into many smaller subsections called finite elements. The finite elements used by HFSS are tetrahedra, and the entire collection of tetrahedra is called a mesh. A solution is found for the fields within the finite elements, and these fields are interrelated so that Maxwell’s equations are satisfied across inter-element boundaries.
