✦ Synopsis
A voltage-dependent current-phase relation for short microbridges, Is(V, ~b) = I0(V) sin (9 + II(V ) cos ~b + I2(V), is calculated on the basis of time-dependent Ginzburg-Landau theory. Used in the current-controlled resistively shunted Josephson junction model such a current-phase relation enables us to explain a number of features in the I-V characteristics of thin-film microbridges. Experimentally we can estimate the upper frequency limit of the Josephson effect in thin-film microbridges.
