摘要：

A method is presented for modeling open periodic structures by using the finite element method truncated by an anisotropic perfectly matched layer (PML). The method can be used to simulate periodic structures with inhomogeneous profile and arbitrary geometries. The PML is shown to be an effective method for mesh termination, even in the presence the grazing and evanescent fields generated by periodic structures. Numerical analysis is conducted for validation and to demonstrate the effectiveness of the proposed method. (C) 2002 Wiley Periodicals, Inc.
