Space Plasma Effects and Interactions With Radio Waves
Abstract
In this report we summarize our research on ionospheric plasma turbulence and effects on radio waves as well as laboratory simulations, conducted at Arecibo, Puerto Rico and at MIT campus. Large-scale plasma turbulence can be generated in the ionosphere by injected HF radio waves, to appear in the forms of various plasma waves (e.g., Langmuir waves, ion acoustic waves, lower hybrid waves, upper hybrid waves etc.); sheet-like plasma density irregularities, depleted magnetic flux tubes, and plasma bubbles. This research has advanced physics of nonlinear electromagnetic wave interactions with magnetized plasmas. Although plasma density irregularity and depleted magnetic flux tubes are locally produced by the injected HF radio waves, they can extend along the Earth's magnetic fields to a large distance, to establish artificial ionospheric ducts for controlled radio wave communications paths. Detailed reports of these research results are given in the listed journal articles.
