## Abstract A marchingβonβinβtime (MOT)βbased scheme for the analysis of transient scattering from closed surfaces characterized by an impedance boundary condition (IBC) is described. The timeβdomain integral equations being solved involve no analytical approximation and are free of spurious soluti
In this article the numerical method for extracting diffraction coefficients of wedge structures is extended to calculate diffraction coefficients of wedges with the corrugated surfaces for which no closedform expressions exist. Extensi¨e numerical results are gi¨en, and they may be useful in design
