Non-linear high-frequency waves in the magnetosphere

摘要

Using fluid theory, a set of equations is derived for non-linear high-frequency waves propagating oblique to an external magnetic field in a three-component plasma consisting of hot electrons, cold electrons and cold ions. For parameters typical of the Earth’s magnetosphere, numerical solutions of the governing equations yield sinusoidal, sawtooth or bipolar wave-forms for the electric field Keywords Magnetosphere - bipolar - sawtooth wave-forms PACS Nos 52.35.Mw - 52.35.Qz - 90.30.Tz Article presented at the International Conference on the Frontiers of Plasma Physics and Technology, 9–14 December 2002, Bangalore, India.
