Abstract
Data are presented on the resistivity of granular aluminum films near the superconducting transition temperature for both dc and 20-GHz excitation. Comparison with a recent theory of the effect of fluctuations on the frequency-dependent resistivity above shows much less excess conductivity than predicted. A possible explanation for the discrepancy may lie in the incorrectness of a currently suggested form for the time-dependent Ginsburg-Landau equation.
