Applications of electrodynamics - elektrodynamiikan sovellutuksia
Spring 2005
Lecturer: Ari Viljanen, Finnish Meteorological Institute
Assistant: Heikki Vanhamäki, Finnish Meteorological Institute
Lectures: Mon 10-12 in D106, Fri 14-16 in D105. First lecture 17.1., last lecture 4.3.
Exercises: Thu 8-10 in D114 (weeks 4-9)
This course illustrates the use of classical electrodynamics with real examples of some recent research topics. The main contents are: Radiating systems (multipole expansion, antenna). Half-space problems (especially geomagnetic applications, generalized methods of images). Dielectric wave guides. Scattering and mixing theories. Prerequisites: Electrodynamics, Mathematical Methods of Physics (FYMM) I-II. Literature: Lecture notes. This course gives 3 study weeks (3 ov).
