Scientific Review on the Ionospheric Absorption and Research Prospects of a Complex Eikonal Model for One-Layer Ionosphere

Figure 4

Plots of the percentage relative deviation [%], between the quasi-longitudinal (QL) approximation for nondeviative amplitude absorption 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 (a) and extraordinary (b) rays [The critical frequency at the Earth’s equator assumes the following values:  MHz,  MHz,  MHz,  MHz,  MHz,  MHz,  MHz,  MHz].
