摘要：
The pulsed electromagnetic radiation from an electric line source above a conducting earth is investigated theoretically. The modified Cagniard method is used to derive closed-form expressions for the electric and magnetic field anywhere above the conducting earth. Numerical results are presented for the electric field for different points of excitation and observation above the earth, as well as for different values of the earth's material parameters, i.e., permittivity and electrical conductivity. It is shown that the effect of the conductivity is of significant importance to the calculation of interfering transient electromagnetic fields in the pressence of a conducting earth.
