“…Several authors have proposed full-wave analyses of superconducting planar transmission lines [3,4], but analysis of superconducting lines on anisotropic substrates is not available. In this paper, an efficient full-wave method is developed t o calculate the effective dielectric constant, attenuation, and characteristic impedance of superconducting microstrip lines on uniaxial anisotropic substrates in which the optic axis is in the plane of substrate at an arbitrary angle with respect to the propagation direction.…”

A computationally efficient full-wave technique is developed to analyze superconducting microstrip lines on M-plane sapphire in which the optic axis is in the plane of the substrate at an arbitrary angle with respect to the propagation direction. To increase the efficiency of the method, the superconducting strip is replaced by an equivalent surface impedance which accounts for the loss and kinetic inductance of the superconductor. Complex propagation constant and characteristic impedance are calculated and compared to both measured results and results obtained by the more rigorous volume-integral-equation method.

This article provides an overview of the microwave applications of high‐temperature superconductor (HTS) technology. The main characteristics of HTS materials are outlined, highlighting the differences between superconductors and normal conductors. The article also presents the most recent progress in the development of HTS filters, multiplexers, cryogenic receivers, delay lines, and antennas. A brief summary of cryocooler technology and cryopackaging requirements is presented. The benefits of using HTS technology in wireless and satellite systems are also discussed. Newcomers to the field are encouraged to continue reading about the subject to understand more about the potential challenges and limitations of this revolutionary technology.
