Abstract :
Parameters of the perfectly matched layer (PML) of circular boundary are rigorously calculated in the paper. The PML consists of a single, double, or triple layer of elements, whose artificial parameters are calculated by minimizing an error function of potential difference between the nodal potentials of the PML and of the original infinite grid
