Very Low Frequency Propagation Research.

Abstract

Contents: Exponential conductivity model ionosphere for terrestrial extremely low frequency propagation Effect of gyro-resonance of D-region ions Frequency spectrum of earth-ionosphere cavity response to electrical storms Perturbation of Schumann resonances by a low conductivity sharply bounded ionosphere Perturbation of Schumann resonances by a small hemispherical step in effective reflecting height of the ionosphere Effect of induced polarization in the ground on waveguide mode constants Complete theory of the terrestrial extremely low frequency noise spectrum Extremely low frequency noise spectrum in the presence of exponential ionospheric conductiv ity profiles Extremely low frequency antennas Conductivity depth profiles in the sea Effect of sea surface motion on sub-surface fields (Confidential Contents Note)
