中文摘要:
数字模拟与沟在一个维的 Ag 电影单身者裂缝结构的光传播改进性质上被执行了。结果证明沟的位置,深度和数字在光传播上有大影响,并且出现电浆子电磁声子和回声模式是主要因素。35.8 dB 的最大的扑灭比率被调整沟深度在单个裂缝结构完成。
英文摘要:
Numerical simulation has been performed on the optical transmission enhancement properties of a one-dimensional Ag film single slit structure with grooves. The results show that the position, depth and number of the grooves have great influence on the optical transmission, and surface plasmon polariton and resonance mode are the primary factors. The maximal extinction ratio of 35.8 dB is achieved in the single slit structure by adjusting groove depth.
