本文介绍了超导微带传输线的频率范围为100-1100 GHz的模拟结果。用该方法计算了不同几何形状的超导微带线的特性阻抗和波传播常数。事实上，建模提供了设计毫米和亚毫米波长的超导微带电路的唯一工具，因为在这种波长和4 K的低温下无法以最终精度直接测量这种线路。铌作为最常用的超导材料，被用于建模，尽管同样的方法适用于任何不同的BCS超导体。为了评估模型的准确性，我们已经做了广泛的比较研究，从早期出版物中已知的超导微带模型，进行数值模拟使用三维EM求解器，HFSS，并使用本文介绍的一个新的模型与所有的模拟结果绘制在文件中。
This paper presents results of superconducting microstrip transmission line simulation for the frequency range 100–1100 GHz. The simulation is used to calculate the characteristic impedance and the wave propagation constant in a superconducting microstrip line having different geometry. Indeed, modelling provides the only tool for designing superconducting microstrip-based circuits at millimetre and sub-millimetre wavelengths because no direct measurements of such a line can be made at this wavelengths and at cryogenic temperature of 4 K with ultimate accuracy. Niobium, as the most commonly exploited superconducting material, was used for the modelling, though the same approach would work for any different BCS superconductor. In order to evaluate the model accuracy, we have made an extensive comparison study of the superconducting microstrip models known from earlier publications, performed numerical simulations using 3D EM — solver, HFSS, and used a new model introduced in this paper with all simulation result plotted in the paper.
