Abstract :
Some numerical and analytical results are presented that illustrate how changes in the coupling strength affect the dynamics of coupled current-biased Josephson point junctions are presented. It is shown that in certain cases there is a unique interval during which the basic running solution for the equations governing the dynamics of the couples system is unstable. The numerical results suggest that there are period-doubling cascades and infinitely many multiple-pulse homoclinic solutions that exist in the interval. These results are described and discussed with respect to chaotic behavior reported for such systems
