We examined the impacts of magnetic and non-magnetic impurities, proximity-coupled thin normal layers, and subgap states on surface resistance, kinetic inductance, and depairing current. I'll discuss the advantageous results for device development, such as minimizing surface resistance by purposefully adjusting depairing factors. These findings have been detailed in publications by A. Gurevich and T. Kubo, Phys. Rev. B 96, 184515 (2017); T. Kubo, Phys. Rev. Research 2, 033203 (2020); and Phys. Rev. Applied 17, 014018 (2022).
