An explicit 2D finite element time domain scheme for electromagnetic wave propagation

An explicit 2D FETD formulation for electromagnetic wave propagation is pre sented. The space dirscretization is obtained using finite element triangle s, The domain is truncated using an Higdon absorbing boundary condition. Th e time discretization is performed using a four level scheme. Mass lumping technique makes it explicit. Several numerical parameters are studied, such as the mesh density, the order of the ABC and the numerical stability.
