| Abstract | Abstract—The time-domain performance of a number of ab-sorbing boundary conditions invoked on the boundary of a domain of computation, as well as of a perfectly matched layer surrounding such a domain, is carried out for a test configuration for which ana-lytic expressions for the relevant field quantities exist. The test con-figuration consists of a small loop antenna radiating into a homo-geneous, isotropic half-space. On the planar boundary of this half-space, either an absorbing boundary condition is invoked or a per-fectly matched layer is started that is truncated at some finite depth of penetration. For a loop parallel to the boundary, closed-form analytic expressions for all field components of the spuriously re-flected field are presented for all truncation conditions involved. A number of important features show up that might be masked in purely numerical implementations of the procedures under consid-eration.
