TY - JOUR TI - Calculation of electric field strength in the ionospheric F-region AU - Yeşil Ali AU - Kurt Kadri JN - Thermal Science PY - 2018 VL - 22 IS - 11 SP - 159 EP - 164 PT - Article AB - In this study, we have calculated the electric field strength, Ey, of a plane electromagnetic wave with frequency, ω, propagation along z-axes and the polarized y-axes in 1-D by using Wentzel, Kramers, and Brillouin method for both with and without collision conditions in ionospheric F-region with regard to seasonal and local time. Also, the refractive index of ordinary wave and attenuation factor was computed for collision and collision-free conditions. When the collisions were calculated in the F-region of the ionosphere, it was observed that the electric field strength decreased for all seasons and Ey increased between 275-400 km altitudes encountering approximately hmF2 “the peak of F2” for the accepted conditions.
