Abstract :
The absorption of a radio wave in the ionosphere can be approximated by A = frac{\\omega }{c}frac{1}{2}\\intfrac{Z(\\mu\´ - \\mu)}{1 + g} \\cos \\alpha ds , where the integral is along the ray that exists when the normalized collision frequency Z = 0, \\mu\´ and \\mu are the group and phase refractive indices, respectively, and \\alpha the angle between the wave normal and ray direction. Graphs are presented from which g can be obtained for any values of the ionospheric plasma parameters X and Y .
