- 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
