Abstract: —The article describes an algorithm for calculating the characteristics of the passage of low-frequency electromagnetic waves through the magnetoactive plane-stratified lower ionosphere. The algorithm is based on numerical integration of wave equations for the case of a plane wave incident on the ionosphere from below, taking into account the plasma’s ionic composition. As an illustration, the basic characteristics of passage of waves in the 0.05–1 kHz frequency range are calculated. It is shown that the power transmission coefficient of these waves is quite large, ranging from 0.2–0.4 for most of the frequencies used. It is shown that in the daytime near a frequency of ~300 Hz, the transmission coefficient in the daytime has a maximum and is approximately double the nighttime values.
