Abstract

We describe new phenomena arising in long and extended Josephson junctions associated with the two-dimensional character of these junctions. Avortex in such junctions has additional degrees of freedom related to its length. We investigate the behaviour of a Josephson vortex in curved waveguides. As a result we have proposed how to increase transmission properties of a curved waveguide. Moreover, there may arise a flux cloning phenomenon. In this phenomenon the vortex may split into two or more new vortices at the special T, Y or any multiple shaped junction. We describe a series of new devices, the operation of which is based on flux cloning.
