This chapter deals with the effects of ionospheric propagation on a radio signal's amplitude and phase structure. Radio signal attenuation in terms of losses e.g. power loss and spatial losses are discussed together with ionospheric absorption and its temporal and spatial variations. Polarization matching and fading are also included. Radio signal frequency in relation to its phase is also given focus. Ionospheric drifts, traveling ionospheric disturbances, acoustic-gravity waves, and nonreciprocal phenomena are also discussed.
