ECE 5160 Introduction to Space Plasmas (3C)
Underlying physical processes in the space environment medium in terms of plasma physics and electrodynamics. Single particle motion, fluid and kinetic theory of plasmas, plasma waves and instabilities, diffusion and resistivity, and a brief introduction to nonlinear effects.
The near-earth space environment has profound effects on radio waves, electrical devices, power systems, satellites, space vehicles, as well as humans. As society becomes more dependent on technologies embedded in this environment, more understanding of physical properties and predictive capabilities in terms of 'space weather' will become crucial. This course in space plasmas provides the student with a description of the near-earth space environment as a medium in terms of plasma physics and electrodynamics. The course covers all important space plasma phenomena including single particle motion, plasma waves and instabilites, diffusion, resistivity, conductivity, collisional processes, as well as a brief introduction to nonlinear effects. Both fluid and kinetic treatments of space plasmas will be provided as well as a brief introduction to computational techiques for space plasmas.
