Abstract:

Tables for the amplitudes and phases of plane waves reflected from a plane, homogeneous earth were calculated using the Fresnel equations. The total fields at the reflecting surface resulting from the combination of the incident and reflected waves were computed for one component of the electric field, and for two components of the magnetic field. The angle of incidence was varied from 0 to 90 degrees in two-degree steps, and the frequency was varied from 5 kHz to 100 kHz in 5-kHz intervals. Computations were made using five combinations of earth conductivity and dielectric constant more or less typical of sea water, fresh water, ice, poor soil, and good soil, assuming a relative magnetic permeability of unity.
