In this paper we investigate the performances of first‐ and second‐order time‐domain absorbing boundary conditions (ABCs) when introduced in a finite‐element algorithm to solve electromagnetic scattering problems. Attention is focused on the analysis of the ABC's absorbing characteristics when different geometries are considered for the truncation of the computational domain. Numerical results will be given by considering, as a first analysis, two‐dimensional scattering problems. © 2003 Wiley Periodicals, Inc. Microwave Opt Technol Lett 38: 11–16, 2003
