Abstract :
The application of the source-model technique to the solution of two-dimensional (2-D) transient scattering problems directly in the time domain is described. Special attention is given to the accuracy and the stability of the numerical solution scheme. A detailed comparison is made between the more often used single-type-source solution scheme and a newly proposed combined-source solution scheme. It is found that the combined-source scheme can offer a significant advantage in terms of stability, without any appreciable loss in accuracy, over the single-type-source scheme
