class geoana.em.fdem.ElectricDipoleWholeSpace(frequency, quasistatic=False, **kwargs)

Class for simulating the fields and fluxes for a harmonic electric dipole in a wholespace.

Harmonic electric dipole in a whole space. The source is (c.f. Ward and Hohmann, 1988 page 173). The source current density for a dipole located at \(\mathbf{r}_s\) with orientation \(\mathbf{\hat{u}}\)

\[\mathbf{J}(\mathbf{r}) = I ds \delta(\mathbf{r} - \mathbf{r}_s)\mathbf{\hat{u}}\]
