Finite element analysis of controlledsource electromagnetic induction for nearsurface geophysical prospecting Academic Article

abstract

• 2002 Society of Exploration Geophysicists. A three-dimensional finite element solution to the coupled-potential (A; ) formulation of Maxwell's diu-sive equations has been developed for controlled-source electromagnetic prospecting in the near-surface region. The solution is formulated in terms of the secondary (As;s) potentials, and is calculated over a simple rectangular tetrahedral mesh. Electric and magnetic fields are recovered with a simple finite dierence. The results have been tested against known analytic solutions with very promising results, and is currently being tested against other available solutions for more complex conductivity distributions.
