Popis

The admittance-wall boundary condition is incorporated in the time-domain contour integral method. It is shown
that the inclusion of the radiating wall amounts to adding a single matrix in the resulting marching-on-in-time scheme. An
illustrative numerical example demonstrates that even a simple instantaneously-reacting uniform edge admittance may improve the validity of results with respect to the standard formulation based on the (closed) cavity model.
