Modeling of electromagnetic field in the Earth-ionosphere resonator (Transmission Line Method)

Abstract

The Schumann resonances – electromagnetic eigenmodes of the resonator bounded by the Earth's surface and lower ionosphere, permanently excited by the global lightning activity – are now widely monitored experimentally. To relate the obtained data with ionospheric parameters the computer modeling of such a resonator is necessary. The various approaches to  this task  are surveyed and some new insights are suggested.
