Resonant emission of a chain of Josephson vortices on an array of inhomogeneities

A theory is derived for the collective effect of resonant emission as a chain of vortices moves in a long Josephson junction along which there are structural inhomogeneities in a periodic arrangement. Experiments reveal structural features on the current-voltage characteristic of a junction with artificial inhomogeneities in an external magnetic field. These structural features are associated with the occurrence of resonances of this sort.
