In this article on ionospheric absorption, there is mention of the inverse square law. That, I am quite sure, is incorrect. The inverse square law, of course, weakens signals increasingly with distance, but it is not the cause of the absorption. The article needs some explanation of the plasma processes that absorb radio waves. For example, what is the absorption coefficient? How does it depend on electron density? How does it depend on frequency?
