摘要

Due to the progress in computational power and a better understanding of the mathematical theory, the time domain boundary element method (TD-BEM) is recently gaining influence in the modeling of radiation phenomena. Parallel programming gave rise to computations of real life problems in a reasonable time. In this paper we choose a simple model problem, namely the retarded single layer ansatz, to explain the underlying space-time Galerkin method as proposed by Ha-Duong, cf.
