Comparison between HIE‐FDTD method and ADI‐FDTD method
Microwave and Optical Technology Letters, 2007AbstractThis letter gives the comparison of the 3D hybrid implicit–explicit finite‐difference time‐domain (HIE‐FDTD) method with the ADI‐FDTD method through numerical examples. It shows that the HIE‐FDTD method has higher accuracy than the ADI‐FDTD method, especially for larger rate of field variation; the time step size, which has a detrimental effect

A Study on Unconditionally Stable FDTD Methods for the Modeling of Metamaterials
Journal of Lightwave Technology, 2009 We assess the performance of three unconditionally stable finite-difference time-domain (FDTD) methods for the modeling of doubly dispersive metamaterials: 1) locally one-dimensional FDTD; 2) locally one-dimensional FDTD with Strang splitting; and (3 ...

1993 IEEE MTT-S International Microwave Symposium Digest, 2002
A finite-difference-time-domain (FDTD) diakoptics method is developed. Sequential and parallel algorithms are provided to connect cascaded segments and to realize the modular computation of large circuits. When the large circuit is modified, only a few segments need to be recalculated, while the mutual interaction is preserved.

Accuracy improved ADI‐FDTD methods
International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, 2006AbstractFDTD method plays an important role for simulation of different structures in various fields of engineering, such as RF/microwaves, photonics and VLSI. However, due to the CFL stability constraint, the FDTD time step is still small and the related CPU time is still large for modelling fine geometry where small cell sizes are required to resolve

Performance evaluation of several implicit FDTD methods for optical waveguide analyses
Journal of Lightwave Technology, 2006 he performance of the recently developed implicit finite-difference time-domain methods (FDTDs) is compared with that of the traditional explicit FDTD. For the implicit methods, the alternating-direction implicit (ADI) FDTD and the envelope ADI-FDTD are ...

Stability analysis for the AIBO‐FDTD method
International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, 2008AbstractThe stability of the implicit finite‐difference time‐domain (FDTD) method named alternating implicit block overlapped (AIBO) FDTD is presented in this paper. Based on separation of variables method, the spectral radius of the growth matrix for AIBO‐FDTD is obtained.

A hybrid FDTD and leapfrog ADI-FDTD method with PML implementation
2011 IEEE MTT-S International Microwave Symposium, 2011In this paper, a hybrid FDTD and leapfrog alternating-direction-implicit finite-difference time-domain (ADI-FDTD) method is presented. The perfectly matched layer (PML) absorbing boundary conditions are also incorporated in the method and non-uniform grids are deployed to efficiently model electromagnetic radiation and scattering in open domains.

A hybrid ADI-FDTD scheme and its comparisons with the FDTD method
IEEE Antennas and Propagation Society International Symposium. Digest. Held in conjunction with: USNC/CNC/URSI North American Radio Sci. Meeting (Cat. No.03CH37450), 2004In this paper a technique that hybrid FDTD and ADI-FDTD methods for a locally graded mesh is proposed for efficient numerical modeling of RF/microwave structures. In it, the conventional FDTD grid is applied in the coarse mesh region, while the ADI-FDTD is used in the locally dense region.
