摘要：

We study rotobreather properties in Josephson ladders with external de currents and nonzero island-island capacitances. These solutions are localized in space, with tails characterized by exponential localization and a wave length which both vary smoothly upon varying the external bias. We demonstrate the existence of resonances fbr underdamped systems which are related to the plane wave spectrum of the nonresistive system. We propose experimental observations of these resonances.
