Popis:	In order to understand the mechanisms which determine the I‐V characteristics of granular bridges, a model was established treating the granular bridge as a network of Josephson junctions. Calculations of many diverse configurations of such networks show that only certain superpositions of voltages of single junctions lead to Shapiro steps in the overall I‐V curves of the network. These steps can be obtained when the granular bridge consists of a few grains only and when the ac current is applied with not too high a frequency. Then, characteristics of single junctions determine the behavior of the network, and Shapiro steps probably will appear.
