Abstract
A rigorous formulation is carried out for a superconducting microstrip line with an arbitrary strip thickness. The superconducting strip is modeled by an equivalent impedance sheet in the formulation. The surface impedance of the sheet is obtained in a general closed form which is a function of the strip parameters. The transmission characteristics of superconducting microstrip lines are calculated using the derived formula and presented for comparison. Numerical results for the phase and attenuation constants of microstrip lines are computed using the two-fluid model for the sake of comparison with other methods. It is concluded that the approach presented here can accurately predict the characteristics of normal conducting and superconducting microstrip lines as well as other planar transmission lines with finite strip thickness.<>
