induced polarization

Induced polarization as electromagnetic phenomenon (general phenomenological theory)

The fact that about thirty years ago geophysicists began to analyze the induced polarization (IP) as an electromagnetic (EM) phenomenon has induced the authors to prepare a current review generalizing the experience. The generalization is done based on General Phenomenological Theory (GPT) of EM Field in Heterogeneous Geological Medium, suggested by the authors. In this case, EM properties of the medium depend on time and frequency of the field.
