Analysis of Simplified SB-ADI Scheme for Two-Dimensional Maxwell's Equations
This letter represents a simplified sampling biorthogonal alternating-direction implicit (SSB-ADI) method based on the sampling biorthogonal time domain (SBTD) algorithm. Two sampling functions with different orders for sampling biorthogonal method are used to display spatial discretization. Dispersion and stability analyses are presented. It is shown through a numerical simulation that SSB-ADI reduced the CPU time and memory compared to the SB-ADI method.

The Simplest V-Cycle Fast Adaptive Composite Grid ADI-FDTD Method for Two-Dimensional Electromagnetic Simulations
An alternating-direction-implicit finite-difference time-domain (ADI-FDTD) method based on the fast-adaptive-composite grid ADI (FAC-ADI) scheme is introduced to reduce the truncation error generated when ADI-FDTD is derived from the Crank-Nicolson (CN) ADI scheme, and its efficiency is investigated. The relaxation equation and residual equation for FAC-FDTD are constructed by defining the error vector between the traditional ADI and CN FDTD formulas, and the iterative formulas are defined using the iterative schemes. A comparison of the computational efficiency between the FAC-ADI and ADI-FDTD is presented.

ADI‐FDTD method perturbed by the second order cross derivative terms
A two‐step FDTD method as a compromise of conditional stability and reduced splitting error is formulated and its numerical stability is investigated. It is the perturbed form to the ADI‐FDTD method by the addition of second order cross derivative term. It is validated from the comparison of numerical anisotropy and numerical error over the ADI‐FDTD that numerical performances can be improved by controlling the perturbed term within the stable region of the cross derivative term. © Wiley Periodicals, Inc.

Reduction of numerical dispersion by optimizing second‐order cross product derivative term in the ADI‐FDTD method
We propose a new adaptive alternating‐direction implicit finite‐difference time‐domain (ADI‐FDTD) to reduce the anisotropy in the numerical phase velocities. The proposed form has two anisotropic parameters on the first order terms of the time step and one parameter on the second order term of the time step. We introduce a new approach of reducing the error of the numerical phase velocity by controlling the three parameters. The numerical stability is discussed and compared with the previous approach of reducing the numerical dispersion. © 2007 Wiley Periodicals, Inc.
