Pagination or Media Count:
The report presents results of a numerical study of EM propagation under diffuse anistropic ionospheres at the extremely low frequencies of 45 Hz and 75 Hz. Waveguide mode parameters are presented under both day and night ambient conditions for several values of ground conductivity as a function of geomagnetic flux density, dip angle, and direction of propagation.
