碩士 === 清雲科技大學 === 電機工程所 === 99 === In this paper, we use multiple physical coupling Comsol Multiphysics simulation software to simulate the finite element method analysis of nano-silver shell dielectric waveguide core of the rhomboidal chain waveguide, measurement Rhombus of silver columns and silver on the electric field between the shell of the inter- value, and change the column solid silver hollow silver shell holes and the media column filled with different dielectric constant, showing a difference in the peak wavelength, peak wavelength to achieve the purposes of regulation; then for S nanowire waveguide with straight numerical model, changing the shape of nano-metal structure and length, and to compare the case of different media materials, the results can be seen that no matter how far the length of the wavelength, to achieve the control transfer efficiency Numerical strength of the near-field intensity level of the value in the use of these waves as the incident light wavelength ultraviolet and visible light from the band for the transmission characteristics of long distance.
