Radio Wave Propagation

Electromagnetic radio waves traveling within earth’s atmosphere are called terrestrial waves, and communications between two or more points on earth is called terrestrial radio communications. Terrestrial waves are influenced by the atmosphere and earth itself. In terrestrial radio communications, waves can be propagated in several ways, depending on the type of system and the environment. Electromagnetic waves also travel in straight lines except when earth and its atmosphere alter their path. This paper, gives detail explanation about ground‐wave, space‐wave and sky‐wave propagation.
