Abstract
Conductivity fluctuations determine the amplitude of the long-time tail in the intermediate scattering function. These fluctuations and the closely related tortuosity fluctuations are shown to set the frequency threshold for the localization of elastic waves in saturated and unsaturated porous media.Keywords
