Anotace:

Nonlinear effects in space plasmas influence generation and propagation of electromagnetic emissions, especially those which are generated with embedded discrete time-frequency structures. Whistler mode chorus is a good example of these waves which are propagating in the Earth's magnetosphere. Chorus and other types of whistler-mode waves can influence the space environment of the Earth by their interactions with particles at different energies.

This PhD thesis work will be mainly focused on analysis of generation and propagation of whistler-mode emissions and their interactions with charged particles, improving thus our fundamental understanding of their behavior and effects.

Specific tasks include:

- Review of the available theoretical and experimental scientific literature in this field - Improvements of the existing data analysis, theoretical or simulation approaches - Comparison of results with the experimental data from spacecraft missions - Presentation of results at international meetings and preparation of publications in scientific journals
