geoana.em.tdem.VerticalMagneticDipoleHalfSpace

class geoana.em.tdem.VerticalMagneticDipoleHalfSpace(time, **kwargs)

Transient of a vertical magnetic dipole in a half space.

Only valid for source and receivers at the surface. The surface is assumed to be at z=0.

Waveform is assumed to be the step off.
