Abstract

An explicit 2D FETD formulation for electromagnetic wave propagation is presented. The space discretization is obtained using finite element triangles. The domain is truncated using a Higdon absorbing boundary condition. The 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
