Electromagnetic Fields Generated By a Vertical Magnetic Dipole Upon the Surface of a Dielectric-Coated Spherical Conducting Earth

Abstract

In this paper, the accurate and complete formulas for the electromagnetic field generated by a vertical magnetic dipole upon the surface of a dielectric-coated spherical conducting earth have been derived. Finally, the computations show that the trapped surface wave can be excited by a magnetic dipole when the thickness of the dielectric layer satisfies the specific conditions.
