Description
High-frequency applications of Josephson contacts require single-valued current-voltage characteristics which are usually achieved by using an external low-resistance normal-metal shunt in parallel with each junction. In this contribution, we propose a new approach for realizing internal shunting in Josephson heterostructures where a barrier itself contains the desired resistive component. We also study the space-time vortex-flow dynamics in elongated Josephson junctions by solving the related sine-Gordon equation with a Baecklund transformation.
