By numerical calculations of the differential‐difference sine‐Gordon equation, we have discussed the discrete Josephson‐junction transmission lines which are constructed of a series of small‐area Josephson junctions connected by superconducting strips. It is shown that the discrete Josephson lines containingDlines,Nlines,Tturning points, andSturning points are elementarily characterized by the discreteness parameter (2&pgr;LIc/&Fgr;0)1/2. On the discrete Josephson logic circuits there exists a region of forbidden propagation in the (2&pgr;LIc/&Fgr;0)1/2‐&ggr; (bias‐current parameter) plane for single flux quanta. A single flux quantum can be stuffed in a small area of the discrete Josephson logic circuits. The discrete circuits can be conveniently and easily linked to each other, in a practical fabrication of a Josephson network.
