Content and learning outcomes
Course contents
Intended learning outcomes
To provide the theoretical basis for waves appearing in plasmas, propagation and absorption of them. When completing the course, the student should be able to
- Derive the dispersion relation for waves in a cold plasmas
- Characterize the more 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 one calculates wave propagation with the ray tracing method
- Describe the collisionless absorption mechanisms in a plasma
- Describe how the emission and absorption processes are related

Ethical approach
- All members of a group are responsible for the group's work.
- In any assessment, every student shall honestly disclose any help received and sources used.
- In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
