Course information

Content and learning outcomes

Course contents *

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.

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.

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

Other requirements for final grade *

Satifactory results on the asssignments during the course andon the written examination. The final mark is weighted from the result of the assignments and the written examination.
