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

Abstract : From attenuation and phase constants for plane waves in a partially-ionized magnetopionic medium, the resultant surface magnetic field for discrete, constant-amplitude input signals at an outer boundary is calculated and presented as power spectra. The ionosphere is assumed stratified, and the only mode considered is the extraordinary mode, propagating at 90 degrees with respect to the earth's magnetic field. The results are discussed with reference to experimental power spectra. (Author)
