 note = {P(論文), Both spatial distributions of the field intensity and the polarization at the ground of a spatially confined whistler mode wave, which has a Gaussian amplitude incident onto the ionosphere from above are computed by a full wave method. The propagation paths in the earth-ionosphere wave guide are estimated by tracing the peaks of these wave distributions at different altitudes. From these calculations, the following interesting results are obtained : (1) The spatial attenuation rate of the wave intensity in the earth-ionosphere wave guide mode is about -10dB/100km for a distance less than a few hundred kilometers from the source. (2) The polarization is right-handed circular just underneath the source point, but it becomes left handed at some distance away.},
