Scientific Review on the Ionospheric Absorption and Research Prospects of a Complex Eikonal Model for One-Layer Ionosphere
Figure 3
Plots of the QL nondeviative amplitude absorption [dB], according to the Settimi et al. [11] complex eikonal model (32), (33), and (34) and Rawer’s [12] theory (20a)-(20b), as a function of the frequency (MHz), for both the ordinary and extraordinary rays. The critical frequency at equator assumes the following values: (a) MHz, (b) MHz, (c) MHz, (d) MHz, (e) MHz, (f) MHz, (g) MHz, and (h) MHz.
