Subcell Treatment of Sloped Interfaces between Debye Materials in the FDTD Method
Journal of Amasya University the Institute of Sciences and Technology, 2020 This paper presents the application of the subcell technique for the treatment of sloped interface in finite-difference time-domain method. The technique is based on the averaging of permittivities in each cell crossed by the material interface.

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(

Comparison of errors and stability in FDTD and FVTD [PDF]
Advances in Radio Science, 2003 The methods of finite-difference time-domain (FDTD) and finite-volume time-domain (FVTD) are well known techniques for solving electromagnetic problems. While for FDTD a number of commercial codes is available there are only few based on FVTD.
