N2 - A major challenge for the experimental realization of advanced superconducting traveling-wave parametric amplifiers is given by proper impedance matching of the input and output transmission lines and the active region with periodically embedded Josephson junction arrays. For a large impedance mismatch, non-negligible reflections occur at the interfaces, leading to a co-propagation of cavity-like modes. In this contribution, we want to assess the effects of improper impedance matching on the transmission spectrum of traveling-wave parametric amplifiers using a simple overlay cavity model. Our results can serve as a guideline for design limitations of Josephson-junction-embedded transmission lines.
