Radio propagation categories. There are a number of categories into which different types of radio propagation can be placed. These relate to the effects of the media through which the signals propagate. 1  Free space propagation: Here the radio signals travel in free space, or away from other objects which influence the way in which they travel. 2  It is only the distance from the source which affects the way in which the field strength reduces.
Wave propagation is any of the ways in which waves travel. With respect to the direction of the oscillation relative to the propagation direction, we can distinguish between longitudinal wave and transverse waves. For electromagnetic waves, propagation may occur in a vacuum as well as in a material medium.
