Abstract
We examine the role of multipolar couplings among brine-filled pores in the low-frequency dielectric anomaly of porous media. We show that the polarizability enhancement caused by these couplings can give rise to a large dielectric response. The effect requires that there be pores separated from each other by thin walls, and its strength is sensitively determined by the microgeometry of the sample.Keywords
