The effect of absorption on radio wave reflection bу the ionosphere for slant proЬing

The rigorous solution to the problem of radio wave propagation in а nonuniform ionospheric layer with а linear profile of permittivity and absorption is considered. The exact solution is oЬtained for the complex reflectivity of the layer. It is shown that, even for а low absorption, the attenuation of radio waves in the layer can Ье quite strong, while reflection is virtually absent.
