Effects of parasitics on the Q -parameters of a three-port circulator. The circulator is matched to the external impedance of 50Ω and the matching is optimized for filling factor \(\nu = 8\). We used here \(C_{p}=2~\mbox{fF}\). As the parasitic capacitances are very small, their effect on the response is negligible, see Figure 6.
