Abstract :
In the numerical solution of electromagnetic scattering and/or radiation problems by finite methods, a mesh truncation scheme must be employed in order to obtain a bounded computational domain. We discuss the realization of perfectly matched absorbers by means of a complex coordinate transformation in a general coordinate system. In this way, it is possible to design perfectly matched layers (PMLs) which are conformal to the antenna/scatterer surface. The performance of the PMLs are tested for certain problems, which are also described.
