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.
