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 $$\mathbf{\hat{u}}$$

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