PARAMETER-ESTIMATION FOR PMLS USED WITH 3D FINITE-ELEMENT CODES

Perfectly Matched Layers (PMLs) are used to truncate the mesh in a 3D edge finite element code. A new interpretation of the PMLs helps to so lve the problem of joining PMLs of different directions and to estimat e the proper setting of the PML parameters. The finite element code us es an A,V description to obtain a better convergence rate of the itera tive solver. The program is used to model the electro-magnetic field o f a linear dipole antenna in the vicinity of lossy objects.
