采用时域有限差分法研究了基于双链金圆柱的等离子体波导。入射高斯光束的波长范围为650 ~ 1200nm，计算了相应的衰减系数。我们还提出了一个90°分裂角的y形分裂器，每个分支都是双链的形式。评估了不同波长下的传输效率。
The plasmon waveguide based on double chain of gold cylinders is studied using the finite-difference time-domain method (FDTD). The wavelength of the incident Gaussian beam ranges from 650 to 1200nm, and the corresponding attenuation factors are calculated. We also present a Y-splitter with 90° splitting angle, each branch in the form of double chains. The transmission efficiencies for different wavelengths are evaluated.
