The synchronization of coupled oscillators is studied in the context of two distinct systems: a one-dimensional array of Josephson junctions shunted by an RLC load and one- and two-dimensional arrays of coupled phase model oscillators. First, hysteresis in Josephson junction arrays is investigated. A long-standing discrepancy between the dynamics of the full equations and the corresponding averaged equations is resolved. By introducing a self-consistency condition into the averaging method, hysteresis is recovered. Comparisons between the numerics of the full equations and those of the self-consistent averaging are quite good. Next, an analog circuit is developed to simulate the dynamics of a one-dimensional array of Josephson junctions shunted by an RLC load. Although the design is readily extendable to N junctions, only two coupled junctions are explicitly considered. The circuit behavior is compared with analytic results obtained via the averaged equations. Finally, the static and dynamic beam steering of one- and two-dimensional arrays of coupled oscillators is studied. It is found that by manipulating the natural frequencies of the army elements, the position of the far-field intensity pattern can be controlled. Explicit solutions to the dynamical equations are obtained. In addition, complete analytic stability analysis results are derived.
