"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. " - Ionosphere waves
