Ionosphere and radio wave propagation
WebPropagation Paths. The radio frequency (RF) energy radiated by a transmitting antenna spreads out with distance. Therefore, radio waves strike the ionosphere at many different angles rather than a single angle. This can result in several different paths between a transmitter and a receiver, including the following: WebKalpana Patel, in Atmospheric Remote Sensing, 2024. Abstract. Earth’s ionosphere plays a crucial role in atmospheric electricity and is an interesting layer to study radio wave propagation or sky wave propagation in space. The space weather activities create changes in the thickness of ionospheric plasma and structure the ionospheric …

Earth’s ionosphere is shielded from the solar wind by a strong planetary magnetic field. In contrast, the Mars ionosphere is directly exposed to the solar wind because Mars lacks a strong magnetic field. Presence of a magnetic field can influence the plasma motion within the ionosphere and also affect low frequency radio wave ...
