Abstract
In this chapter, the region of interest consists of a spherical and electrically homogeneous Earth, coated with a dielectric layer, and air above. Both the dipole (vertical electric dipole, vertical magnetic dipole, or horizontal electric dipole) and the observation point are assumed to be located on or near the spherical surface of a dielectric-coated Earth. The approximate solution for the electromagnetic field at low frequencies is obtained. Analysis and computations are carried out specifically.
