一个基本的计划是用来有效地实现频率相关的三维局部一维FDTD方法。在所得方程的右手边以无矩阵算子的形式执行该公式化。一个改进的程序，其中隐式和显式方程交替计算，只需要保留10个场阵列，而传统的显式FDTD需要12个。对一个间隙等离子体波导的分析验证了所提出的三维LOD-FDTD方法的有效性。
A fundamental scheme is utilised to efficiently implement the frequency-dependent 3D locally one-dimensional FDTD method. The formulation is performed in matrix-operator-free forms in the right-hand sides of resultant equations. A modified procedure, in which implicit and explicit equations are alternately calculated, needs to retain only 10 field arrays, while the traditional explicit FDTD requires 12. Analysis of a gap plasmonic waveguide validates the presented 3D LOD-FDTD method.
