Two-dimensional time-domain scattering using the nyström method and finite difference delay modeling

Over the past decade, much research has been done to improve the efficiency and stability of time domain integral equations (TDIEs) [1, 2]. Despite the advances made due to this work, some problems remain extremely difficult to solve accurately. For instance, the time-domain Green's function of two-dimensional (2D) transverse electric (TE) scattering posseses a high-order singularity and a temporal infinite tail making standard approach difficult to apply.
