A method is described for calculating the resonance characteristics of the earth‐ionosphere cavity. Particular attention is paid to the influence of the geomagnetic field which, for purposes of the analysis, is assumed to be purely radial. In the model used, the ionosphere is represented as a homogeneous concentric shell, which is regarded as a cold electron plasma with collisions. It is found that the geomagnetic field lowers the real resonance frequencies from those for the corresponding isotropic model.
