Fluxon Scattering on a Stripe-Like Impurity in a Two-Dimensional Josephson Junction

Section: Nonlinear processes
Original Author's Text: English

Abstract: The interaction of a soliton (fluxon) with a stripe-like inhomogeneity in a two-dimensional Josephson junction is studied. The radiation emitted due to the fluxon scattering on the impurity is calculated. The total radiation energy shows a distinct resonant dependence as a function of the fluxon velocity. The current-voltage characteristic of such a junction with a fluxon trapped in it is calculated. The signature of the emitted radiation on the current-voltage dependence is analyzed.

Key words: fluxon scattering, stripe-like impurity, two-dimensional Josephson junction.
