Locally-conformal perfectly matched layer implementation for finite element mesh truncation

In this article, we introduce the locally conformal perfectly matched layer (PML) technique, which is an easily implementable conformal PML implementation, obtained via complex coordinate transformation, for the purpose of mesh truncation in the finite element method. After deriving the governing equations, we test this technique using electromagnetic scattering problems. (C) 2006 Wiley Periodicals, Inc
