| Abstract: | Summary A local planar approximation of a stratified, inhomogeneous, anisotropic and dissipative ionosphere is presented as an Alfven
quarter-wave plate resonator in the Pc1 micropulsation range. The frequency-amplitude structure of the resonance response
of an isotropic Alfven wave on the Earth's surface and at a given altitude in the ionosphere is studied in comparison to standing
waves in vacuum above an ideal conductor for a particular model of the ionosphere. An asymmetry in the response was found
at both boundary of the resonator, at the Earth's surface and at the given altitude z0. The results are related to the vertical changes of frequency dispersion in the dissipative medium of the ionosphere and
to the vertical profile of the inhomogeneities of the resonator being considered. |
