Ionospheric bending basics | What is Ionospheric bending
This page describes ionospheric bending basics.
The ionosphere is a region, just above our atmosphere, were there are significant number of free electrons and ions. The number of ions and electrons are equal, hence there is no net charge.
• When a RF (Radio Frequency) signal travels into ionospheric layer, it experiences refraction due to
differences in the density between layers.
• Radio wave experiences force from ions in ionospheric layer.
• If RF signal is incident at correct angle at this layer, it gets reflected back to our inner atmosphere due to total internal reflection.
• This phenomenon is utilized in mobile communication for radio frequency propagation.
• This ionospheric reflection is called as ionospheric bending.
