Antennas And
Wave Propagation
The three basic paths that the radio signal can take are ground wave (or surface
wave), sky wave (or ionospheric wave) and space wave. In this chapter we will
take a review of ground wave propagation. 8.2 Concept of Propagation of Radio

7.3.1 Ground Wave Propagation The ground wave is a vertically polarized wave
that travels along the surface of earth, as shown in Fig. 7.28. If propagation by
ground wave is desired, then vertical antennas are used. A horizontally polarized

Ground Penetrating Radar Theory and Applications
Under certain circumstances, the initial ground wave signal can become 'clipped'
as the GPR receiver system saturates with strong ground coupling, and therefore,
the recorded trace does not represent the true peak amplitude of the returning ...

Complex Electromagnetic Problems and Numerical Simulation ...
The problem has been addressed in [29], where the three components of the
ground wave are expressed in cylindrical co-ordinates [11]. The exact solution to
the problem of an antenna above a spherical finitely conducting earth can be set
up ...

Radio-electronic Transmission Fundamentals
The Ground Wave at High Frequencies When we examine the effect that the
transmission frequency has upon the attenuation of a ground-wave signal (Fig.
44-4), we are greatly- impressed by the poor performance of the higher
frequencies.
