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 ...
