Reflection of sinehyphen;Gordon breathers

摘要

The influence of a boundary on a breather traveling in a Josephson line cavity is examined by means of numerical computations. For a passive termination the breather is reflected into a breather of less energy; when the characteristic impedance of the line equals the external load resistor the breather is almost annihilated. At an active termination the breather is reflected into a breather of increased energy possibly followed by fluxons, antifluxons, or even breathers.
