Ionosphere waves
Web1 jan. 2013 · The ionosphere is a dispersive medium with respect to microwave signals. This means that the propagation of microwave signals through the ionosphere depends on the frequency of the signals. In order to quantify these effects, the refractive index of the ionosphere must be specified. Web2 jun. 2024 · Scientists still use ground-based radio waves to study the ionosphere from afar. Learning about the neutral atmosphere, however, usually requires going there – or …
