WebWe now know a little about the mechanism for refraction from the ionosphere. When a radio wave reaches the ionosphere, the electric field in the wave forces the electrons in the ionosphere into oscillation at the same frequency as the radio wave. Some of the RF energy is given up to this resonant oscillation. WebThe ionosphere was discovered when it was observed that radio waves can propagate over large distances, and one therefore had to assume the existence of an electrical conductive layer in the upper atmosphere which could reflect the waves. datatang beijing technology co. ltd
