Abstract. Taking into account the oscillating polarization current in Maxwell's equations made it possible to determine the “transparency band” of the ionosphere by the angle between the direction of the magnetic field and the wave vector for VLF radio waves. Waves with both linear polarization of the electric field vector and an extraordinary wave can penetrate to heights above the maximum of the ionosphere layer. The absorption of radio waves is largely determined by the magnitude of the angle between the geomagnetic field vector and the direction of propagation of the radio wave. When radio waves propagate strictly along the geomagnetic field line, an extraordinary wave is not absorbed, but a wave with linear polarization is absorbed. Calculations make it possible to explain the maxima of the energy spectrum of radio waves recorded by the DEMETER satellite in the area of the transmitter location and in the area of the magnetically conjugate point.
Keywords: VLF radio waves; ionosphere, Earth's radiation belts, permittivity, conductivity.
