An implicit FDTD method based on the locally one-dimensional (LOD) scheme has been developed for the efficient analysis of three-dimensional (3-D) plasmonic devices. The trapezoidal recursive convolution technique has been adopted, in which a single convolution integral is required. In addition, a fundamental scheme has been introduced for efficient formulation of the algorithm, in which no spatial derivative exists in the right-hand side of the equations. The developed LOD-FDTD offers a reduced computation time from 85 min with the conventional explicit FDTD to 37 min for the analysis of a plasmonic gap waveguide. The characteristics of several 3-D plasmonic devices have been investigated using the LOD-FDTD. The 3-D results have been compared with those of 2-D models, showing the necessity of the 3-D analysis for an accurate evaluation of the plasmonic devices.

已经开发了一种基于本地一维（LOD）方案的隐式FDTD方法，以有效地分析三维（3-D）等离子设备。采用了梯形递归卷积技术，其中需要单个卷积积分。此外，已经引入了基本方案，以有效制定该算法，其中该方程的右侧不存在空间衍生物。开发的LOD-FDTD可将计算时间从85分钟减少，用于分析等离子间隙波导的常规显式FDTD至37分钟。已经使用LOD-FDTD研究了几个3-D等离子体设备的特性。将3-D结果与2-D模型的结果进行了比较，显示了3-D分析的必要性，以准确评估等离子设备。
