Fluxon dynamics in discrete Josephson transmission lines with stacked junctions
- Institute of Thin Film and Ion Technology, Research Center (KFA), D-52425 Juelich (Germany)
The experimental and numerical study of parallel one-dimensional arrays consisting of double-layer stacked small Josephson tunnel junctions is reported. In addition to several features already known for classic single-layer arrays, we find a new resonant state which corresponds to the locking of the fluxon oscillations to a frequency of small-amplitude oscillations of the superconducting phase in middle islands of small stacks. Numerical simulations of a simplified circuit agree well with experiments and confirm the suggested qualitative mechanism. In these experiments we find no indication for the so-called multiple-fluxon propagation in double-junction arrays.{copyright} {ital 1997 American Institute of Physics.}
