A new hybrid implicit-explicit FDTD method for local subgridding in multiscale 2-D TE scattering problems [PDF]
, 2016 The conventional finite-difference time-domain (FDTD) method with staggered Yee scheme does not easily allow including thin material layers, especially so if these layers are highly conductive.

International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, Volume 33, Issue 2, March/April 2020., 2020 Abstract A unified 3‐D alternating‐direction‐implicit finite‐difference time‐domain algorithm with one‐step leapfrog approach is provided for analyzing the frequency‐dependent dispersive media. The dielectric parameter in the frequency domain is described by the modified Lorentz model.

Geofluids, Volume 2020, Issue 1, 2020., 2020 The finite‐difference time‐domain (FDTD) method adopts the most popular numerical model simulating ground penetrating radar (GPR) wave propagation in an underground structure. However, a staircase approximation method is usually adopted to simulate the curved boundary of an irregular object in the FDTD and symplectic partitioned Runge‐Kutta (SPRK ...

ADI-FDTD method including linear lumped networks
Electronics Letters, 2006 A three-dimensional alternating-directional-implicit finite-difference time-domain (ADI-FDTD) method including linear lumped networks is presented. In addition, a numerical experiment is performed for validation of the proposed scheme, as well as the higher computation efficiency achieved.
