| Summary: | As the size of superconducting nanowire devices increases and the influence of second-order effects, such as thermal or electrostatic coupling, becomes more significant, the complexity of models required to accurately and efficiently simulate the device’s behavior becomes more challenging. Traditional circuit simulators used for superconducting devices tend to focus on frequency-domain simulation and are not optimized for simulating superconducting nanowire geometries in the time-domain. This thesis presents an integrated simulator environment designed with the goal of simulating superconducting nanowires. The work presented in this thesis introduces:
1. an integrated environment for SPICE software that extends its modeling capabilities optimized for superconducting nanowire devices and accompanying experiments;
2. a simple procedure to measure the stability of circuit models used to present an improved nanowire SPICE model; and
3. an efficient Julia-based simulator optimized for superconducting nanowire devices and nonlinear microwave circuits. |
