Improved Unconditionally Stable FDTD Method for 3-D Wave-Propagation Problems

Combining standard with optimised split‐step finite‐difference time‐domain methods for the study of graphene configurations

“…Instead, some works focus on accuracy enhancement by developing alternative strategies. For example, the LOD-FDTD method is upgraded in [29] by optimising wave propagation along the three axes, while novel spatial operators with extended stencils are designed in [30], which accomplish a wideband correction of the ADI-FDTD algorithm.…”
