A Compact Unconditionally Stable Method for Time-Domain Maxwell's Equations [PDF]

open access: yesInternational Journal of Antennas and Propagation, 2013
Higher order unconditionally stable methods are effective ways for simulating field behaviors of electromagnetic problems since they are free of Courant-Friedrich-Levy conditions. The development of accurate schemes with less computational expenditure is

Second-Order Unconditionally Stable Direct Methods for Allen–Cahn and Conservative Allen–Cahn Equations on Surfaces [PDF]

open access: yesMathematics, 2020
This paper describes temporally second-order unconditionally stable direct methods for Allen–Cahn and conservative Allen–Cahn equations on surfaces. The discretization is performed via a surface mesh consisting of piecewise triangles and its dual-surface

Numerical dispersion analysis of the unconditionally stable 3-D ADI-FDTD method [PDF]

open access: yesIEEE Transactions on Microwave Theory and Techniques, 2001
This paper presents a comprehensive analysis of numerical dispersion of the recently developed unconditionally stable three-dimensional finite-difference time-domain (FDTD) method where the alternating-direction-implicit technique is applied. The dispersion relation is derived analytically and the effects of spatial and temporal steps on the numerical ...

Efficient unconditionally stable one‐step leapfrog ADI‐FDTD method with low numerical dispersion

open access: yesIET Microwaves, Antennas & Propagation, 2014
An efficient unconditionally stable one‐step leapfrog alternating‐direction‐implicit finite‐difference time‐domain (ADI‐FDTD) method based on the controlling parameters is presented. First, three controlling parameters are introduced to the matrices of the Maxwell's equations to decrease the numerical dispersion error, and then the formulation of an ...
