The propagation of SLF/ELF electromagnetic waves is introduced in various media like the earth-ionospheric waveguide, ionospheric plasma, sea water, earth, and the boundary between two different media or the stratified media. Applications in the earthquake electromagnetic radiation and the submarine ...
Abnormity of super low frequency (SLF) and extremely low frequency (ELF) electromagnetic radiation on the satellite has been discovered before the earthquakes occur by the earthquake prediction researchers. In order to estimate the effects on the electromagnetic radiation in the lower ionosphere associate...

In Chap.5, the propagation of SLF/ELF electromagnetic waves in the anisotropic ionosphere is treated analytically and numerically. Considering that the main parameters of the ionosphere, including electron and ion densities, electron and ion collision frequencies, changed significantly with the height ...
In order to estimate the effects on the electromagnetic radiation in the lower ionosphere associated with the seismic activity, SLF/ELF waves radiated from a possible seismic current source modeled as an underground horizontal electric dipole (HED), are precisely computed by using a speeding numerical...
Excitation and Propagation of SLF/ELF Electromagnetic Waves in the Earth–Ionosphere Waveguide/CavityIn Chap.2, the region of interest is a waveguide or cavity between the Earth's surface and an isotropic homogeneous ionosphere. Both the dipole source and the observation point are assumed to be ...
In Chap.7, we will summarize our recent works on the radiation of an electric dipole in infinite anisotropic plasma and the electromagnetic field on the sea surface generated by the space borne transmitter in SLF/ELF ranges. A space borne SLF/ELF transmitter for the communications to submarines...
Considering the similarity between the propagation of SLF/ELF waves and that of VLF wave, the VLF waveguide propagation theory and its applications in submarine communication was introduced, especially including the work by J.R.Wait. Then, we introduce the theory of SLF/ELF wave propagation in ...
