The HIE-FDTD Method for Simulating Dispersion Media Represented by Drude, Debye, and Lorentz Models
Nanomaterials, 2023 The hybrid implicit–explicit finite-difference time-domain (HIE-FDTD) method is a weakly conditionally stable finite-difference time-domain (FDTD) method that has attracted much attention in recent years. However due to the dispersion media such as water,

Frequency‐dependent finite‐difference time‐domain method based on iterated Crank–Nicolson scheme
Electronics Letters, 2023 The finite‐difference time‐domain (FDTD) method based on the iterated Crank–Nicolson (ICN) scheme is extended to a frequency‐dependent version. The Drude model is used to express a metal dispersion, which is incorporated into the iterated Crank–Nicolson ...
