The peculiarities of power terrestrial ELF emission in the Earth’s ionosphere


" About 40 years ago the power lines harmonic radiation (multiple of 50/60 Hz) was found at satellite observations in a few kilohertz range, nevertheless the ionosphere was considered fully opaque for extremely low frequency (ELF) EM emission. However recently, in spite of theoretical estimations, the SR harmonics and power line emission (PLE) 50/60 Hz were discovered during flights of low Earth orbiting satellites C/NOFS (Simões et al., 2011) and Chibis-M (Dudkin et al., 2015) at heights 400-800 km, i.e. over F2-layer."

" Last results are a great challenge to the theory of ELF EM emission propagation in the Earth’s ionosphere as well as for study of long-term influence of constantly increasing electric energy consumption by human civilization in the Earth’s environment."
