Abstract
We present data from one-dimensional unshunted Josephson-junction arrays with ground planes, showing resonant behavior for certain values of the critical current. Due to the hysteresis of the current-voltage characteristics, the number of junction that oscillate on resonance can be controlled. The resonant frequency decreases as more junctions are switched onto the resonance and increases as the array length is increased. We develop a transmission-line model of the arrays that reproduces these experimental observations. We also examine the microscopic origin of this model and compare it to existing models in the literature.
