induced polarization

The paper aims to develop an algorithm for identifying the physical (polarizability and resistivity) and geometric (center of mass, orientation, and dimensions) characteristics of local heterogeneities. This is achieved by analyzing induced polarization (IP) potential field data measured at the boundary of the object, using the indirect near-boundary element method. Methodology. A piecewise homogeneous half-plane was chosen as a model of the Earth's crust, where the components are in non-ideal contact.

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.
