An anisotropic perfectly matched layer-absorbing medium for the truncation of FDTD lattices
TL;DR: In this paper, a perfectly matched layer (PML) absorbing medium composed of a uniaxial anisotropic material is presented for the truncation of finite-difference time domain (FDTD) lattices.
Journal ArticleDOI
Convolution PML (CPML): An efficient FDTD implementation of the CFS–PML for arbitrary media
J. Alan Roden,Stephen D. Gedney +1 more
TL;DR: A novel implementation of perfectly matched layer (PML) media is presented for the termination of FDTD lattices based on the stretched coordinate form of the PML, a recursive convolution, and the use of complex frequency, shifted (CFS) PML parameters.
Book
Introduction to the Finite-Difference Time-Domain (Fdtd) Method for Electromagnetics
TL;DR: This book guides the reader through the foundational theory of the FDTD method starting with the one-dimensional transmission-line problem and then progressing to the solution of Maxwell's equations in three dimensions.
Journal ArticleDOI
An Anisotropic PML Absorbing Media for the FDTD Simulation of Fields in Lossy and Dispersive Media
TL;DR: In this article, a uniaxial anisotropic perfectly matched layer (PML) absorbing material is presented for the truncation of finite-difference time-domain (FDTD) lattices for the simulation of electromagnetic fields in lossy and dispersive material media.
Journal ArticleDOI
An unconditionally stable finite element time-domain solution of the vector wave equation
Stephen D. Gedney,U. Navsariwala +1 more
TL;DR: In this paper, an implicit finite element time-domain (FETD) solution of the time-dependent vector wave equation is presented, which employs a time-integration method based on the Newmark-Beta method.
