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.

摘要—本文介绍了一种计算低频电磁波通过磁化平面分层的下部电离层的通道特性的算法。对于平面波从下方入射到电离层的情况，考虑到等离子体的离子组成，该算法基于波动方程的数值积分。作为说明，计算了0.05-1 kHz频率范围内的波通过的基本特性。结果表明，这些波的功率传输系数非常大，大多数使用的频率范围为0.2-0.4。结果表明，在白天，频率约为300 Hz，白天的传输系数最大，大约是夜间值的两倍。
