An application of the perfectly matched layer (PML) concept to the finite element method frequency domain analysis of scattering problems. Abstract: The Perfectly Matched Layer (PML) concept, introduced by Berenger with the aim of synthesizing an absorbing boundary condition (ABC) for the Finite Difference Time Domain (FDTD) method,CiteSeerX Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We introduce a conformal perfectly matched layer (PML) for the finiteelement timedomain (FETD) solution of transient Maxwell equations in open domains. The conformal PML is implemented in a mixed FETD setting based on a direct discretization of the firstorder coupled Maxwell curl equations (as opposed to the second conformal perfectly matched layer for the mixed finite element time-domain method

The parametric analysis of the electrical conductivity distribution for the Perfect Matched Layer (PML) method, is discussed in this communication. The Berengers PML defines a new computational space around the area of interest yielding to reduce any undesirable reflection that may perturb the main computational domain. The optimal parameters values for the conductivity distribution are

We provide a performance analysis for the conformal perfectly matched layer (PML) applied to the mixed finitedifference timedomain (FETD) method. The mixed FETD method is based on the first order coupled Maxwell's equations and include both Perfectly Matched Layer (PML) Berenger introduced the concept of a perfectly matched layer (PML) for reflectionless absorption of electromagnetic waves, which can be employed as an alternative to the transparent boundary condition (TBC).conformal perfectly matched layer for the mixed finite element time-domain method Conformal Perfectly Matched Layer for the Mixed Finite Element TimeDomain Method Article (PDF Available) in IEEE Transactions on Antennas and Propagation 56(4): 1017 1026

IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, VOL. 56, NO. 4, APRIL 2008 1017 Conformal Perfectly Matched Layer for the Mixed Finite Element TimeDomain Method conformal perfectly matched layer for the mixed finite element time-domain method Based on conformal construction of physical model in a threedimensional Cartesian grid, an integralbased conformal convolutional perfectly matched layer (CPML) is given for solving the truncation problem of the open port when the enlarged cell technique conformal finitedifference timedomain (ECTCFDTD) method is used to simulate the wave propagation inside a perfect electric conductor Oct 10, 2004  A new perfectly matched layer (PML) formulation for the time domain finite element method is described and tested for Maxwell's equations. In particular, we focus on the time integration scheme which is based on Galerkin's method with a temporally Layeroriented Element Integration Algorithm of Conformal Perfectly Matched Layer. To reduce computing effort of CPML, this article proposes a layeroriented element integration algorithm. In this algorithm, the relative dielectric constant and permeability are considered as constants
