✦ Synopsis

The double layer impedance between a perfectly polarixable metallic electode and an electrolyte exhibits anomalous behavior as a function of frequency o. This behavior is related to the surface roughness of the electrode. We introduce a random walk algorithm for calculating this frequency behavior as a power series in (1 -io)-I. We apply this algorithm to the calculation of the impedance of a two dimensional slot and of fractal aggregates: in the first case the calculated impedance shows the expected o -'j2 constant phase angle (CPA) behavior. The impedance of the aggregates shows more complex behavior.

## Abstract The study of the structure of the electrode–solution interface usually involves the measurement of the differential capacity–potential characteristics of the system. In order to obtain the double‐layer parameters from these data, integration and differentiation procedures are required a
