Abstract:

The electric and magnetic field components produced by vertical and horizontal dipoles both electric and magnetic types located at or above the surface of a plane, conducting, homogeneous earth are derived for the near field range. The height h of the transmitting antenna is or 0, while the depth z of the receiving antenna is or 0- air-to-subsurface propagation. ionospheric effects are neglected. The derivations are based upon application of the reciprocity theorem to previously derived field components. It is observed that these equations reduce to well-known expressions when the horizontal separation between the transmitting and receiving antennas is much greater than h.
