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

Error reduced ADI-FDTD methods
IEEE Antennas and Wireless Propagation Letters, 2005The Courant-Friedrich-Levy (CFL) stability condition makes the explicit finite-difference time-domain (FDTD) methods computationally expensive in applications where small cell sizes are needed to resolve high variations of fields. To circumvent the problem, unconditionally stable alternate-direction implicit (ADI)-FDTD method has been recently proposed.

Dispersion-Error Optimized ADI FDTD
2006 IEEE MTT-S International Microwave Symposium Digest, 2006ADI-FDTD method is efficient in solving fine RF/microwave structures due to its unconditionally stable characteristics. However, it suffers from large dispersions with the increase of time steps. In this paper, an error-minimized ADI-FDTD method is proposed that is less dispersive as compared to the conventional ADI-FDTD method.

Symmetric source implementation for ADI-FDTD
IEEE Antennas and Propagation Society Symposium, 2004., 2004The alternating-direction-implicit finite-difference time-domain (ADI-FDTD) method is attractive for simulations involving highly refined grids due to its unconditional stability (Namiki, T. 2000; Zheng, F. et al., 2000; Darms, M. et al., 2002). It has been recently reported that the ADI-FDTD method may lead to asymmetrical results in the field ...

A parameter optimized ADI-FDTD method
IEEE Antennas and Wireless Propagation Letters, 2003We present a parameter optimized alternating-direction implicit (ADI)-finite-difference time-domain (FDTD) method. This parameter optimized ADI-FDTD algorithm can minimize the dispersion error for arbitrary incident angles and for different time-step sizes.

ADI-FDTD Method for Transformed Maxwell's Equations
The 2006 4th Asia-Pacific Conference on Environmental Electromagnetics, 2006The Crank-Nicolson method is applied to the field transformed Maxwell's equations to derive an ADI FDTD scheme. The proposed method significantly reduces the limitation on time step size and the computational domain to only one period of the structure. Using the von Neumann technique, the numerical stability of the proposed method was studied.

On the dispersion relation of ADI-FDTD
IEEE Microwave and Wireless Components Letters, 2006In this letter, we analyze the alternating direction implicit finite-difference time-domain (ADI-FDTD) dispersion relation and find the numerical plane-wave relationship between the magnetic and electric fields, showing that the scheme is not divergence-free.
