Abstract

The theory of the multilayer shielded and open microstrip lines considering the superconductor strip on semiconductor regions is presented. The Transverse Transmission Line (TTL) is used in the analysis. The superconductor effect is included with the boundary condition of the surface impedance that is related to the complex conductivity of the material, calculated from the advanced two-fluid model. Applying the moment method the complex propagation constant of the structure, including the phase constant and the attenuation constant, is obtained. Results are presented for the complex propagation constant, versus the frequency and the temperature, of this multilayer superconducting microstrip line.
