| Abstract: | The multicomponent data of the electromagnetic field obtained on the Aureol-3 satellite were studied. On the basis of the application of the multispectral analysis, nonlinear interactions on the harmonics of the proton gyro-frequency were determined. By the power spectra of the low frequency radiation components, the principal regulations of behaviour of the vectors of the wave normal and of the wave distribution function from the frequency and the invariant latitude L were found. It is noted, that at frequencies below the proton gyro-frequency there often arises the second maximum in the form of a wave distribution function, that can be interpreted as a reflected wave. |
