Intended learning outcomes

To provide the theoretical basis for waves appearing in plasmas, including their propagation and absorption. When completing the course, the student should be able to

  • Derive the dispersion relation for waves in cold plasmas
  • Characterize the most common cold plasma waves
  • Be familiar with the CMA diagram
  • Solve wave equation in a planar geometry with WKB
  • Describe how to treat the plasma response and basic properties of the response tensor
  • Describe how to calculate wave propagation with the ray tracing method
  • Describe the collisionless absorption mechanisms in a plasma
  • Describe how the emission and absorption processes are related

Course main content
