We present the results of ground-based observations of low-frequency electromagnetic fields from ionospheric source initiated by powerful HF radio-waves emitted by EISCAT facility. The report is dealing with the results of the heating experiment carried out by AARI in October 2014. The components of the ELF/VLF electromagnetic field have been recorded by the observatories in the PGI high-latitude stations network: namely in the “Lovozero”, the “Verkhnetulomsky”, and also at the Barentsburg station (Svalbard, Norway). The electromagnetic field parameters, such as circular polarization index of the horizontal magnetic field and wave impedance at the frequencies of 1017, 2017, and 3017 Hz, are considered. The results of observations are compared with the results obtained by modeling of the electromagnetic ELF/VLF waves generation and their propagation in the Earth-ionosphere waveguide.
