We present a spectral‐domain analysis of thin superconducting microstrip structures in which the effects of superconducting materials, finite conductivity, and finite thickness are taken into account, using the concept of complex surface impedance. Numerical simulations showing variation of the propagation and attenuation characteristics of transmission lines and the quality factor of resonators with regard to temperature and frequency are presented. Some of the theoretical results are compared with the available data to document the validity of the approach. © 2004 Wiley Periodicals, Inc.
