Abstract
The use of an anisotropic material for the boundary truncation of the finite element method is considered, The anisotropic material properti es can be chosen such that a planewave incident from free space into t he anisotropic halfspace has no reflection, Because there is no reflec tion, the material is referred to as a perfectly matched layer (PML). The relationship between the anisotropic PML and the original PML prop osed by Berenger [2] is considered, The anisotropic PML is applied to the finite-element solution of electromagnetic (EM) scattering from th ree-dimensional (3-D) objects, Numerical results are presented to demo nstrate the accuracy of the PML.
