Encyclopedia > Ionospheric reflection

Ionospheric reflection: Of electromagnetic waves propagating in the ionosphere, a redirection, i.e., bending--by a complex process involving reflection and refraction--of the waves back toward the Earth.


Note: The amount of bending depends on the extent of penetration (which is a function of frequency), the angle of incidence, polarization of the wave, and ionospheric conditions, such as the ionization density.


Source: from Federal Standard 1037C

Ionospheric reflection is taken into consideration as well.
The ionosphere reflects frequencies in a certain band, which often changes due to solar conditions.
Because the solar wind "blows" the ionosphere toward the Earth on the day side, and away from it on the night side, this natural radio "mirror" is much closer to the surface during the day.
