RÉSUMÉ

The paper deals with the problem of finding a correct and efficient way to restrict the computational window in the finite difference time domain (FDTD) method applied to the analysis of transient waves in infinite two-dimensional domains containing compact inhomogeneities. The developed approach is based on the formulation of exact absorbing boundary conditions on the grid in the Cartesian coordinates and its incorporation to the computational scheme.
