The refractive index of mixture in presence of the electron temperature in ionospheric plasma

In this study, the refractive index of mixture in presence of the electron temperature in ionospheric plasma has been investigated, especially for the D-region of ionosphere. The refractive index of mixture had been studied for various angles (0 degree, 30 degrees, 60 degrees and 90 degrees). It can be say that the electron temperature hasn't been consisting a difference(=in presence of electron temperature and in absence of electron temperature) for 0 degrees but for the other angles (30 degrees, 60 degrees and 90 degrees), the electron temperature has been considerable consisting difference. This difference has been affecting the behavior of the electromagnetic waves in the point of view both resonance and reflection of wave
