Coupled seismic and electromagnetic wave propagation

Coupled seismic and electromagnetic wave propagation is studied theoretically and experimentally. This coupling arises because of the electrochemical double layer, which exists along the solid-grain/fluid-electrolyte boundaries of porous media. Within the double layer, charge is redistributed, creating an excess electrical charge in the fluid...

Seismoelectric Modelling of the Flux-Normalized P-SV-TM Propagation Mode

Elastodynamic and electromagnetic processes are coupled together in saturated, porous media, by a phenomenon known as the electrokinetic effect. In horizontally layered media, the seismoelectric system, which contains the coupled elastodynamic and electromagnetic systems, can be separated into two independent modes of propagation: SH-TE and P-SV...

Source Decomposition and Receiver Composition for Electro-Kinetic Measurements

At interfaces between porous media acoustic energy can be converted into electromagnetic energy or vice versa by the electrokinetic effect. Operators exist describing this conversion, however these act on (one-way) upgoing and downgoing waves, while in nature only the total (two-way) wavefield exists. In this thesis mathematical formulations are...
