+        **libdlf** is a library for digital linear filters. Codes until now had
+        to hard-code their digital linear filters. This has several
+        disadvantages. Having a common library that can be used by any code
+        base in any language should hopefully widen the adoption of linear
+        filters, make their use more reproducible, and might hopefully even
+        spark the design of new, hopefully more robust filters or filters for
+        new applications.

+        **elfe3D** is a 3D forward modelling code that can simulate electric
+        and magnetic field responses from frequency-domain controlled-source
+        electromagnetic geophysical setups. It uses tetrahedral meshes and
+        first-order finite-element approximations. In addition, adaptive mesh
+        refinement approaches are implemented.

+
+        **EMmod**, which stands for electromagnetic modeling, is an algorithm
+        to model the full electromagnetic field in a vertical transverse
+        isotropic (VTI) layered medium. Although the algorithm was designed for
+        frequency-domain marine Controlled Source Electromagnetics (CSEM), it
+        can also be used to simulate data for other geophysical exploration
+        methods like for example Ground Penetrating Radar (GPR). The algorithm
+        computes the EM-field analytically in the wavenumber-frequency domain
+        and then carries out a numerical Hankel transformation to get the
+        space-frequency domain representation.

+        The software **iEMmod** is a non-linear conjugate-gradient algorithm to

+        The forward solver used is our open-source layered-Earth
+        electromagnetic modeling code EMmod.

+
+        **ElSeisHom3D** stands for computing the Green's functions of
+        electromagnetic fields and elastic waves that are coupled in a
+        homogeneous porous medium. The fields are the electric field, the
+        magnetic field, the particle velocity, the filtration velocity, the
+        acoustic pressure in the fluid, and bulk stress. The sources that
+        generate these fields are the electric current source, the magnetic
+        current source, the force source acting on the bulk, the force source
+        acting on the fluid, the acoustic volume injection rate source acting
+        on the fluid, and the deformation rate source acting on the bulk. The
+        impulse responses that connect the fields to these sources are the
+        Green's functions.
