Parallel processing for the simulation of problems involving scattering of electromagnetic waves Original Research Article

The three-dimensional simulation of the scattering of electromagnetic waves by obstacles of arbitrary geometrical shape is considered. Maxwellʹs curl equations are solved in the time domain on an unstructured mesh of linear tetrahedral elements. The discrete equations are formed by a Galerkin procedure, with a Lax-Wendroff consistent numerical flux function and explicit time stepping. Parallelisation of the procedure is achieved by mesh decomposition and the use of a single program multiple data model. The approach is first validated and is then applied to problems involving the scattering of plane electromagnetic waves by a complete aircraft.
