Intended learning outcomes

The objective is to give a deeper understanding and knowledge of treating electromagnetic processes in the areas of plasma physics, astrophysics, radio astronomy and physical optics. After finishing this course the students should be able to treat problems of wave propagation, absorption and emission of electromagnetic waves in anisotropic media.

Course main content

Vektorpotential, Gauge conditions, Maxwell´s equations on tensor form och Maxwell´s tension stensor, multipole expansion, Fourier transforms, generalised functions, Green functions, Laplace transforms, contur integration, response stensors, Kramers-Kronig relations, the Onsager relation, dispersive media, crystals, cold plasma, isotropic warm plasma, wave equation, dispersion relation, polarisation, polarisation of transverse waves, geometric optic, resonances, cut-off, damping of waves, energy flows also in spatial dispersive media, waves in anisotropic crystals, waves in plasma (MHD waves and Langmuir waves), energy of waves, absorption, spontaneous  and stimulated emission, Larmor formula, the Einstein´s coefficients, Landau damping, cyclotron damping, Lienard-Wierchert potentials.

Eligibility

Introductory courses in electromagnetic theory, including vector analysis.

Recommended prerequisites

Courses about mathematical methods in physics and functions of complex variables are recommended.

Literature

Electromagnetic processes in dispersive media, D. B. Melrose and R. C. McPhedran, Cambridge University Press 1991.
