Web23 okt. 2008 · Previous in situ measurements of HF-heating-generated ELF/VLF signals have included those at low altitudes observing signals propagating from the source to the satellite without reflection from the ground [James et al., 1984] and those at laterally distant locations, involving propagation in the Earth-ionosphere waveguide and continuous … WebAbstract. In this paper, we investigate the ionospheric heating by oblique incidence of powerful high-frequency (HF) radio waves using three-dimensional numerical simulations. The ionospheric electron density and temperature perturbations are examined by incorporating the ionospheric electron transport equations and ray-tracing algorithm. …
