TY - JOUR TI - Analytical solutions of the refractive index in the ionosphere different approximations AU - Kurt Kadri JN - Thermal Science PY - 2022 VL - 26 IS - 101 SP - 125 EP - 129 PT - Article AB - From the square of the refractive index, this research presents many solutions for the refractive index of the ionosphere, which has a complex structure. It analyzes the square of the refractive index at a distance of 240 km in the ionosphere using the most often used ordinary wave. When the refractive index is required, the second and first scenarios of the refractive index were found to be the most suited.
