Abstract

This paper presents a phenomenological equivalent circuit to model the phenomenon occurring when a section of superconducting transmission line transits from the superconductor to the normal state. This phenomenon allows the use of superconductors for the design of auto-limiting structures based on superconducting transmission line sections. Although this auto-limiting effect happens when the current density achieved in the superconductor exceeds the critical current inherent to the superconducting material, a significant heating effect also plays a significant role on this behavior. The equivalent circuit presented in this work accounts for both phenomena, electric and thermal effect and the interaction between them. The circuit model is then used for the evaluation of a practical microwave and frequency selective IMUX configuration.
