Fiske modes in one-dimensional parallel Josephson-junction arrays.

Vortices play a central role in determining the static and dynamic properties of two-dimensional (20) superconductors. Artificially fabricated networks of superconducting islands weakly coupled by Josephson junctions are model systems to study the behavior of vortices. Studies of vortices in Josephson junction arrays generally neglect the magnetic fields induced by currents flowing in the array, Le., it is assumed that the penetration depth for flux A is much larger than the size of the array. With the present SNAP technology, all niobium arrays have been made with A of the order of the cell size, therefore, effect of induced fields must be considered for an accurate description of these systems.
