Unified GSTC-FDTD Algorithm for the Efficient Electromagnetic Analysis of 2D Dispersive Materials [PDF]
Journal of Electromagnetic Engineering and Science, 2023 The finite-difference time-domain (FDTD) method has been widely used for the electromagnetic wave analysis of complex media. Conventional FDTD analyses of very thin two-dimensional (2D) dispersive materials require overwhelming computing resources ...

Partially Implicit FDTD (PI-FDTD) Method for Lower Dispersion and Anisotropic Errors
IEEE Access, 2022 A new partially implicit 3D FDTD (PI-FDTD) method is introduced. The method is not unconditionally stable, but its stability limit is 6 times higher than that of the classic Yee’s FDTD method.
