ADI-FDTD algorithm for three-dimensional scattering analysis

6th International SYmposium on Antennas, Propagation and EM Theory, 2003. Proceedings. 2003, 2003
In this paper, the ADI-FDTD algorithm is applied to simulate scattering of three-dimensional objects. A few key techniques include the introduction of an incident plane wave, connective boundary condition between total-field zone and scattering-field zone and near-to-far field transformation are discussed. It is shown from the numerical result that the

Experience of implementing PML for parallel ADI-FDTD

2009 IEEE Antennas and Propagation Society International Symposium, 2009
The family of PML boundary conditions remains important not only to standard FDTD but also to new and emerging parallel implicit FDTD methods. We have applied CPML for the first time to parallel ADI-FDTD code, finding that it is preferable to slightly increase the computational load at the saving of communication overhead, by calculating PML buffer ...

Crank-Nicolson Reformulation of ADI-FDTD PML Extensions

IEEE Antennas and Wireless Propagation Letters, 2006
The usual approach found in the literature to extend the perfectly matched layers (PMLs) absorbing technique to the alternating direction implicit finite-difference time-domain (ADI-FDTD) method employs the so-called ADI-FDTD procedure. In this letter, we show that these extensions can also be systematically reformulated as perturbations of Crank ...

A hybrid 2-D ADI-FDTD subgridding scheme

6th International SYmposium on Antennas, Propagation and EM Theory, 2003. Proceedings. 2003, 2003
The finite-difference time-domain (FDTD) method gives accurate results but uses a large amount of computer memory and time, which can be reduced by applying higher resolution only around critical areas in the problem domain. In this paper, a new subgridding scheme have been proposed which based on the hybridization of the alterative-direction implicit ...

Numerical Analysis for an Improved ADI-FDTD Method

IEEE Microwave and Wireless Components Letters, 2008
The numerical performance of an improved alternating direction implicit finite-difference time-domain (ADI-FDTD) method is studied in this letter. Theoretical analysis shows that this method is unconditionally stable and has low splitting error. Compared with the regular ADI-FDTD method, this method is a better splitting formulation for the Crank ...

PEC condition implementation for the ADI‐FDTD method

Microwave and Optical Technology Letters, 2007
AbstractThe perfect‐electric‐conductor (PEC) condition implementation for the alternating‐direction‐implicit finite‐difference time‐domain (ADI‐FDTD) method is discussed in this article. By comparing different implementation strategies, it shows that the most accurate implementation method is that the PEC condition is directly incorporated within the ...

Symmetric source implementation for the ADI-FDTD method

IEEE Transactions on Antennas and Propagation, 2005
The alternating-direction-implicit finite-difference time-domain (ADI-FDTD) method has been introduced to overcome the Courant limit present in the standard FDTD scheme. However, the ADI-FDTD scheme may produce small asymmetries in the field distributions according to the source implementation.
