Abstract

The paper considers methodological issues of solving the inverse problem of electromagnetic sound, based on the results of measuring the low-frequency magnetic field from two orthogonal antennas located on the Kola Peninsula in areas with different conductivity of the lithosphere. The polarization characteristics of the tangential magnetic field components are determined. They are compared with theoretical calculations using a plane-layered model of a wave propagation medium with homogeneous layers. Comparison of the theoretical calculations with the experimental data on the major axis of the polarization ellipse yields results consistent with existing concepts of the conductivity of the Kola Peninsula. Differences in the direction of the ellipse and ellipticity require complication in the model: the inclusion of faults in the lithosphere, as well as the anisotropy of the structures forming it.

线性振动器激发的ELF–SLF磁场的极化特性

摘要

本文基于对岩石圈电导率不同的区域中位于科拉半岛的两个正交天线的低频磁场的测量结果，考虑了解决电磁声反问题的方法论问题。确定切向磁场分量的极化特性。使用具有均质层的波传播介质的平面分层模型，将它们与理论计算进行了比较。将理论计算与极化椭圆长轴上的实验数据进行比较，得出的结果与可乐半岛电导率的现有概念一致。椭圆和椭圆度方向的差异要求模型复杂：包括岩石圈中的断层，
