Accurate development of the UPML absorbing boundary conditions in a 3D-FDTD algorithm for CPW and microstrip line on silicon substrate

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 pape...

Description
Summary: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. © 2005 Wiley Periodicals, Inc.
