Electromagnetic Fields from a Horizontal Electric Dipole

Electromagnetic field components and polarization ellipse for a horizontal electric dipole

This function computes all six of the electromagnetic field and the polarization ellipse parameters for a point or finite horizontal electric dipole source lying within a source layer (nominally, the ocean but could be an air layer if the HED is located at the bottom of the layer), overlain by an insulating halfspace, and underlain by a layered structure with variable thicknesses and electrical conductivity. Details may be found in the Hed_ell m-file within the zip bundle, and in AD Chave, Geophys. J. Int., 179, 1429-1457, 2009.
