Abstract

Fluxon propagation in Long Josephson Junctions (LJJ) has been thoroughly investigated in past years both as a model system for soliton dynamics1 and in view of possible practical applications2. The electrodynamics of a LJJ is described by a perturbed version of the well known sine-Gordon Equation (PSGE), its kink solution corresponding to a magnetic flux quantum propagating in the junction barrier. Recently has attracted considerable interest solitons propagation in arrays of small coupled Josephson junctions3. In this paper we focus our attention on a system constituted of by a one dimensional array of coupled Josephson Junctions, designed in such a way to generate microwave radiation through a controlled fluxon dynamics.
