摘要
We present a theoretical investigation and application of an unsplit formulation of the perfectly matched layer absorbing boundary conditions (PML ABC), developed here especially for lossy-media FDTD simulations. From the uniaxial PML (UPML) theory, and unlike Berenger's technique, in this paper the anisotropic absorbing medium is based on a Maxwellian formulation. In order to validate the theoretical findings, we have investigated a coplanar waveguide (CPW) on low-cost and low-resistivity silicon substrate.. Moreover, we compare our results with other published works. (C) 2005 Wiley Periodicals, Inc.
