Features of the Spectra of Ultra-Low-Frequency Magnetic Fields from Horizontal Current Sources: Models of Planar and Spherical Earth–Ionosphere Waveguides

Abstract: We simulate the magnetic field components in the frequency range 0.1-30 Hz from a source such as the horizontal magnetic dipole located in the Earth-ionosphere cavity. Models of uniform spherical and planar waveguides are considered, the advantages of each model are determined, and a comparative analysis of the simulation results is performed. The results of numerical calculations lead to the conclusion about the impact of the IAR (ionospheric Alfvén resonator) and sub-IAR (resonator at altitudes of 80-300 km)… Show more

“…Electromagnetic field propagation from an ELF emitting dipole along the Earth‐ionosphere waveguide has been well‐modeled theoretically (Bernstain et al., 1974; Ermakova et al., 2021; Nickolaenko et al., 2016; Sobchakov et al., 2003; Tereshenko & Tereshenko, 2017). In these works, the ionosphere was modeled as a conductive homogeneous layer or an impedance wall.…”
