The ionosphere and radio propagation

Ionosphere is an important component of the upper atmosphere and of the solar terrestrial. It plays a unique role in earth’s environment because of its strong coupling quality to the regions below and above it. Ionosphere plays a significant role in radio communication and has great intrinsic scientific interest which makes it of extensive study during past 50 years. So various topics concerning the propagation, generation and detection of high frequency radio waves in the ionosphere has been discussed here. It has been practiced to know, what happens when radio waves interact with ionosphere, how their refraction takes place, and what are the conditions necessary for radio communication etc.
