The propagation of low frequency electromagnetic waves in the cavity of celestial bopdies with ionospheres has been studied, namely for inferring thunderstorm and lightning activity.

The measurement of resonant states provides useful information for the analysis of the electric environment in the cavity. We present a 3D finite element model of the cavity, compute the lowest eigenfrequencies and Q-factors, and illustrate the spectrum produced by localized electromagnetic sources.
