Ionospheric transmission of transversely propagated plane waves at micropulsation frequencies and theoretical power spectrums

From attenuation and phase constants for plane waves in a partly ionized magnetoionic medium, the resultant surface magnetic field for discrete, constant-amplitude input signals at an outer boundary is calculated and is presented as power spectrums. The ionosphere is assumed to be stratified, and the only mode considered is the extraordinary mode, propagating at 90° with respect to the earth's magnetic field. The results are discussed with reference to experimental power spectrums.
