Analysis of ELF field variations in Eastern Russia

摘要

The results of ELF measurements in the east of Russia using the electromagnetic field of the "Zeus" installation at frequencies of 33, 44, 82 and 188 Hz are considered. A highly sensitive apparatus for amplitude-phase measurements of the surface impedance of the earth's crust is considered. The analysis of field variations in the far zone of the source is carried out. To explain the field variations, calculations of the propagation of ELF radio waves for the model of an inhomogeneous waveguide are performed. A comparison of the calculated and measured values of H_τ shows their good agreement.
