Electromagnetic models for superconducting millimetre-wave and sub-millimetre-wave microstrip transmission lines

We compare and contrast various techniques for calculating the behaviour of superconducting millimetre-wave and sub-millimetre-wave microstrip transmission lines. A rigorous method based on conformal transformations is presented. The results of the analysis are compared with Wheeler's recession technique and the spectral domain method. The strengths and weaknesses of the various approaches are discussed.
