摘要

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 correspondjng attenuation factors are calculated.We also present a Y-splitter with 90° splitting angle,each branch in the form of double chains.The transmission effiencies for different wavelengths are evaluated.
