A multiple-input hybrid plasmonic OR logic gate has been constructed, analyzed, and simulated utilizing the finite element method by using the COMSOL software package version 5.5. To realize the suggested three- and four-input hybrid plasmonic OR gate, constructive and destructive interference has been standard among the input ports and control port. The factors used to evaluate the functionality of the nanoscale gate are the contrast ratio, modulation depth (MD), and insertion losses (ILs). In contrast, the optical power ratio at the output port, known as the transmission value ( value), has been measured and used to distinguish between logic 1 (ON-state) and logic 0 (OFF-state). The transmission threshold value in this article was 25%, and the wavelength range considered to display the result was from 1000 to 2000 nm. The three-input hybrid OR gate occupied a size of 500 ×400 with transmission amplification results from the best value of 216.5 % with 98.85% as a MD. In comparison, the four-input OR gate comes with a size of 600 ×400 at the best value of 301.5%, supported by a 99.33% as the MD. The IL values for the three-input and four-input designs are -4.07 and -5.4 , respectively. The system resonance wavelength is 1310 nm.

已经使用 COMSOL 软件包版本 5.5 通过有限元方法构建、分析和模拟了一个多输入混合等离子体 OR 逻辑门。为了实现所提出的三输入和四输入混合等离子体 OR 门，输入端口和控制端口之间的建设性和破坏性干涉已经成为标准。用于评估纳米级门功能的因素是对比度比、调制深度 (MD) 和插入损耗 (IL)。相比之下，输出端口处的光功率比，称为传输值 ( value)，已被测量并用于区分逻辑 1 (ON 状态) 和逻辑 0 (OFF 状态)。本文中的传输阈值为 25%，考虑显示结果的波长范围为 1000 到 2000nm。三输入混合 OR 门的尺寸为 500×400nm，具有传输放大效果，最佳值为 216.5%，MD 为 98.85%。相比之下，四输入 OR 门的尺寸为 600×400nm，最佳值为 301.5%，MD 为 99.33%。三输入和四输入设计的 IL 值分别为-4.07 和-5.4。系统共振波长为 1310nm。
