WebSky wave propagation is one of the radio wave propagation. It is defined as the behavior of radio waves as they propagate from one point to another or into various parts of the atmosphere. Radio waves propagation can be classified as follows: Ground waves propagation Skywave propagation Free space propagation What is space wave … WebOne path, XYZ, is the basic ground wave. Another path, XEA, refracts the wave at the E layer and passes it on to the receiver at A. Still another path, XFZFA, results from a greater angle of incidence and two refractions from the F layer. At point Z, the received signal is a combination of the ground wave and the sky wave. These two signals ...
