Surface impedance of the Earth''s crust in the ELF range of the radio waves in the East of Russia
Application of controlled ELF sources for theoretical and experimental studies of ELF electromagnetic fields in the East of Russia to expand significantly is proposed. It is noted that research in the ELF range has of mutual interest for the theory and practice of radio communication with the submerged objects into conductive media and deep electromagnetic research of the earth's crust.
