ELF/ VLF hiss is a well-known form of electromagnetic emission having constant spectral density in the limited frequency band, which produces hissing sound [1]. Basically it is a whistler mode wave that interacts with energetic electrons in the magnetosphere. It is known that the result of thes...

Measurements of Multi-frequency signals and multiple sources Please note that most of the High-frequency electromagnetic radiation meters that I encountered to date (both professional and simple) are not able to measure multiple frequencies and multiple radiation sources correctly (mobile, WIFI, cellular...

Preliminary results are described on an investigation of electromagnetic environment in the frequency range from 30 Hz to 90 kHz, which was carried out in Kiruna and its suburbs in Sweden in November 1982. Several suitable places for the ground-based observation of natural wave phenomena were found...
A network devoted to a continuous monitoring of LF, VLF transmitters and ELF signals was set up in Central Italy, and has been operating since 2006, which is currently composed of 9 stations in 9 different Italian cities. From the beginning of 2012, improvements have been carried out on the...
and ELF frequencies, revealing two types of electromagnetic waves, a trans-verse right-handed guided mode, and a linearly polarized compressional mode. The propagation of bothtypes of signals is sensitive to the magnetic field in ways consistent with propagation from a distantsource to the spacecraf...
