Course Information

Description

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 nonlinear effects.

Why take this course?

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 near-earth space environment as a medium in terms of plasma physics and electrodynamics.
