In this study, an equivalent linear and non‐linear circuit model of superconducting microstrip T‐junction (SMT) structures is proposed. Two types of SMT structures are analysed using suggested model and their scattering behaviour is compared using both the method of moment and the finite‐element method (FEM). The fundamental and third‐order harmonic outputs are obtained using harmonic balance method to observe the non‐linear behaviour in SMT structures. A linear and non‐linear model for enhanced SMT structures is also suggested and verified by S ‐parameters comparison between the model and FEM method. The non‐linearity in enhanced structures is modelled similarly and compared with results of normal structures.
