Abstract
Analytic solutions for a fluxon in a long Josephson junction in the presence of surface losses ( term) as well as shunt losses ( term) are obtained by assuming a triangular current-phase relation. This theoretical result provides exact information on fluxon properties (e.g., the line shape, velocity, etc.), independent of the magnitude of and . We find that if is smaller than a critical value, the fluxon behavior is similar to that of the case, but if is larger, quite different behavior is observed, particularly in the high-velocity region.
