Abstract

A model for the propagation of LF-MF radio waves over ice paths with a spatial change in impedance is proposed and substantiated by numerical calculations. Its features are determined for a two-layer “ice-sea” radio path with a spatial change in ice thickness. The surface impedance, the attenuation function W and the field level |Ez| over a two-layer ice path are considered with a spatial change in ice thickness at a frequency of 300 kHz according to: a) harmonic law and b) sawtooth change in ice thickness. The simulation results are necessary to estimate the conditions for the propagation of LF-MF-HF radio waves along the paths of the Northern Sea Route.
