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.

提出了一种基于局部一维（LOD）格式的隐式FDTD方法，用于三维等离子体器件的有效分析。采用梯形递归卷积技术，其中需要一个单一的卷积积分。此外，一个基本的计划已被引入有效的制定的算法，其中没有空间导数存在于右手边的方程。所开发的LOD-FDTD提供了一个减少的计算时间从85分钟与传统的显式FDTD到37分钟的等离子体间隙波导的分析。用LOD-FDTD方法研究了几种三维等离子体器件的特性。的3-D的结果进行了比较与2-D模型，显示的必要性的3-D分析的等离子体激元器件的准确评估。
