Abstract 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.
