Abstract
Readily evaluated exact solutions of the sine‐Gordon equation are presented for nonlinear standing‐wave oscillations on a fixed length of a lossless Josephson transmission line with open‐circuit boundary conditions at the ends. Three distinct species of standing waves are described: (i) plasma oscillation, (ii) breather oscillation, and (iii) fluxon oscillation. Fluxon oscillations can absorb power from an external source of bias current; for this case the volt‐ampere characteristics relating bias current to average junction have been computed.Keywords
