Abstract
A new procedure is presented to account for the radiation condition of unbounded media analysed using the finite- element method in the time domain. The medium is divided into a finite region that is of interest in the analysis, and the remaining unbounded medium. The stiffness contribution of the latter is properly represented by its boundary influence matrix, which is directly calculated in the time domain. This procedure is suited for situations in which many analyses of the finite region must be performed.
