We study the frequency dependence of the electrical impedance at a rough metallic electrode. Using the Rayleigh-Fano approximation to treat the boundary conditions at a rough surface, we get an impedance which depends on the roughness correlation function and exhibits anomalous behaviour under suitable condition. Explicit forms are considered and discussed

Abstract
We study the frequency dependence of the electrical impedance at a rough metallic electrode. Using the Rayleigh-Fano approximation to treat the boundary conditions at a rough surface, we get an impedance which depends on the roughness correlation function and exhibits anomalous behaviour under suitable condition. Explicit forms are considered and discussed
