A Leapfrog Formulation of the 3D ADI-FDTD Algorithm
2007 Workshop on Computational Electromagnetics in Time-Domain, 2007AbstractWe introduce a new, alternative form of the 3‐D alternating direction implicit finite‐difference time‐domain (ADI‐FDTD) algorithm that has a number of attractive properties for electromagnetic simulation. We obtain a leapfrog form of the time‐advance equations, where the E and H fields are staggered at half‐integer and integer time steps ...

Pre-iterative ADI-FDTD method for conductive medium
IEEE Transactions on Microwave Theory and Techniques, 2005An efficient accuracy-improvement scheme is proposed to analyze electromagnetic problems with conductive medium. This scheme is based on interpreting the alternating-direction implicit finite-difference time-domain (ADI-FDTD) method as a special iterative solver for the Crank-Nicholson scheme. By applying an additional number of iterations to locations

Development of a higher‐order ADI‐FDTD method
Microwave and Optical Technology Letters, 2003AbstractIn this paper, a higher‐order alternative‐direction‐implicit (ADI) finite‐difference time‐domain (FDTD) method is presented. The dispersion analysis is performed and the results are compared with those derived from the regular ADI‐FDTD method.

Absorbing boundary conditions in leapfrog ADI-FDTD method
2017 Progress in Electromagnetics Research Symposium - Fall (PIERS - FALL), 2017In this paper, the performance of the absorbing boundary conditions (ABC's) in leapfrog alternating direction implicit (ADI) finite-difference time-domain (FDTD) method is investigated in detail. In the leapfrog ADI-FDTD method, the ABC's must be applied to both the electric and magnetic field.

ADI-FDTD Formulation for General Dispersive Media
2006 IEEE Antennas and Propagation Society International Symposium, 2006The alternating-direction implicit finite-difference time-domain (ADI-FDTD) method is a promising unconditionally stable scheme that may improve the computational efficiency. However, no general dispersive media were considered in the ADI-FDTD community.

The 1D ADI-FDTD Method in Lossy Media
IEEE Antennas and Wireless Propagation Letters, 2008A stability and numerical dispersion analysis for the one-dimensional alternating-direction implicit finite-difference time-domain method in lossy media is presented. To conduct a general study, the conduction term is approximated by a weighted average in time.

2D ADI-FDTD algorithm in generalized nonorthogonal coordinates
2005 IEEE Antennas and Propagation Society International Symposium, 2005In this paper, a 2D generalized nonorthogonal ADI-FDTD (GADI-FDTD) algorithm is proposed to solve scattering problems of complicated objects. Updating formulas of the GADI-FDTD method for TE wave is presented.

Instable 3D ADI-FDTD open-region simulation
2005 IEEE Antennas and Propagation Society International Symposium, 2005The alternating direction implicit finite-difference time-domain (ADI-FDTD) method has been introduced as an unconditionally stable FDTD algorithm. It was shown through numerous works that the ADI-FDTD algorithm is stable both analytically and numerically even when the Courant-Friedrich-Levy (CFL) limit is exceeded.

An iterative ADI-FDTD with reduced splitting error
IEEE Microwave and Wireless Components Letters, 2005We present a new iterative alternating-direction-implicit finite-difference time-domain (ADI-FDTD) method. By recognizing the ADI-FDTD method as a special case of a more general iterative approach to solve the Crank-Nicolson (CN) FDTD scheme, the splitting error in ADI-FDTD can be reduced systematically.
