Properties of the Lateral Electromagnetic Field of a Vertical Dipole and Their Applications

The Formullas For The Electromagnetic Field In Region 1 (Z ≥ 0, K1) Due To A Vertical Electric Dipole Also In Region 1 Near Its Plane Boundary With Region 2 (z ≤
₀
, K2; |K2|

) Are Reviewed. The Corresponding Formulas For The Field In Region 2 Are Then Determined. Use Is Made Of This Field To Determine The Locus Of The Poynting Vector And The Maximum Depth Of Penetration Into Region 2 Of The Lateral-Wave Part Of The Field. Application Is Made To The Use Of The Vertical Antenna In The Sea For The Measurement Of The Conductivity Of The Oceanic Crust.
