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 solve the problem of joining PMLs of different directions and to estimate the proper setting of the PML parameters. The finite element code uses an A,V description to obtain a better convergence rate of the iterative solver. The program is used to model the electromagnetic field of a linear dipole antenna in the vicinity of lossy objects.
