Alternating Magnetic Field

The lecture deals with problems in electromagnetics described by Maxwell's equations, including regimes of low frequency, that are electrostatics and quasi-electrostatics, and of high frequency, that is electromagnetic wave propagation or optics. For a numerical description of the elliptic partial differential equations (PDEs) behind, we use finite elements and the variational framework they are based on. It is the aim that the participants are able to implement own finite element code(s) in Matlab/Octave in 2D and understand why the modelling by finite elements leads to accurate approximations of electrostatic potentials electromagnetics fields.
