The influence of boundary-conditions on resonant frquencies of cavities in 3-D FDTD algorithm using nonorthogonal coordinates. [PDF]
, 1994 The 3-dimensional finite-difference time-domain method in non-orthogonal co-ordinates (non-standard FDTD) is used to calculate the frequencies of resonators. The numerical boundary conditions of the method are presented.

IET Microwaves, Antennas & Propagation, 2021 To obtain high accuracy and efficiency in the simulations, an optimum time step should be taken in finite‐difference time‐domain (FDTD) methods. The authors investigated how time steps impact on numerical dispersion of two FDTD methods including the FDTD(

An Artificial Anisotropy Four-Step HIE-FDTD Method With Lower Numerical Dispersion Error
IEEE Access, 2020 In this article, by introducing artificial anisotropic (AA) parameters in the four-step hybrid implicit-explicit finite-difference time domain (HIE-FDTD) method, an AA four-step HIE-FDTD method is proposed, which can reduce the numerical dispersion error
