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 $Y$ .
