Transient electromagnetic field of a vertical magnetic dipole above a plane conducting Earth

The pulsed electromagnetic radiation from a vertical magnetic dipole above a conducting Earth is investigated theoretically. The modified Cagniard method is used to derive closed form expressions for the magnetic Hertzian vector anywhere above the conducting Earth. Numerical results are presented for the magnetic Hertzian vector for different points of excitation and observation above the Earth, as well as for different values of the Earth's material parameters, namely, permittivity and electrical conductivity.
