The inductance model of coupled high-Tc superconducting microstrip lines

A simple analytical model of odd and even mode external inductance and kinetic inductance for coupled high-temperature superconducting (HTS) microstrip lines is developed. The kinetic inductance model is derived with the extended incremental inductance rule which is applied in a different way for different conductor thickness. The odd and even mode inductance, self- and mutual inductance, characteristic impedance, and attenuation constant are computed with the presented model expressions and the results agree well with that in published literature.
