Abstract

In this paper, dispersion relation of ionic waves of O and NO⁺ is considered in the plasma of E – region Ionosphere. First, we obtain dispersion relation of ionic waves in the presence of earth’s magnetic field. With calculating refractive index of E – region plasma in any height, we obtained average frequency k in these heights. Finally, diagram of ionic frequency O and NO⁺ is drawn.
