Electromagnetic methods play an important role in mineral exploration and are widely used
in the search for metallic resources such as copper, molybdenum, lead-zinc, bauxite …

A meaningful solution to an inversion problem should be composed of the preferred
inversion model and its uncertainty and resolution estimates. The model uncertainty …

Electromagnetic methods that utilize controlled sources have been applied for natural
resource exploration for more than a century. Nevertheless, concomitant with the recent …

We present a finite-element solution to the 3D electromagnetic forward-modeling problem in
the frequency domain. The method is based on decomposing the electric field into vector …

Unstructured tetrahedral grids with local refinement facilitate the use of total-field solution
approaches to geophysical electromagnetic (EM) forward problems. These approaches …

Shear-wave splitting provides insight into geodynamic processes such as lithospheric
deformation and upper mantle flow. This study presents shear wave splitting parameters …

This paper presents a linear edge-based finite element method for numerical modeling of
3D controlled-source electromagnetic data in an anisotropic conductive medium. We use a …

We have developed the open-source toolbox custEM (customizable electromagnetic
modeling) for the simulation of complex 3D controlled-source electromagnetic (CSEM) …

We present a robust and scalable solver for time-harmonic Maxwell's equations for problems
with large conductivity contrasts, wide range of frequencies, stretched grids and locally …

The fast and accurate 3-D magnetotelluric (MT) forward modelling is core engine of the
interpretation and inversion of MT data. In this study, we develop an improved extrapolation …
