Abstract :
The absorption of a radio wave in the ionosphere can be approximated by 
, where the integral is along the ray that exists when the normalized collision frequency 
and 
are the group and phase refractive indices, respectively, and 
the angle between the wave normal and ray direction. Graphs are presented from which 
can be obtained for any values of the ionospheric plasma parameters 
and
