Propagation characteristics of superconductive interconnects

Research output: Contribution to journalArticlepeer-review


Under the assumptions of weak magnetic fields and temperatures well below the critical temperature of the superconductors, the propagation characteristics of a set of N coupled superconducting strips are calculated using an integral equation approach. The proposed theory provides accurate results for frequencies up to a few GHz. Magnetic field calculations allow us to predict acceptable values for the currents in the strips. Comparison with the propagation characteristics of aluminum strips demonstrates the major advantages of superconducting transmission lines, namely, negligible losses and dispersion, and higher phase velocities. Such properties are highly desirable in the engineering of fast interconnects for modern high‐speed integrated circuits.
