TL;DR: In this paper, a general expression for the group refractive index of the ionosphere has been deduced, considering the relevant quadrants for the phase difference between the normal and the abnormal components of the magnetic vector of the radio wave.

TL;DR: In this paper, a formula is derived from which the group index for normal incidence, including collision effects, can be easily computed as a function of μ and χ for frequencies below one megacycle.
