| Outline of Final Research Achievements |
Three dimensional optical electromagnetic simulation of a circular truncated conical fiber with both asymmetric MIM structure and twin nano-hole at the apex of the fiber has been performed by COMSOL Multiphysics coupled with Wave Optics Module. The systematic calculation will give us valuable counsel for control of surface plasmon polaritons (SPPs) appearing around the MIM structure and twin nano-hole. (1) Optimal design of the 3D model for Xeon server and rational approach for the FEM analysis, (2) behavior of SPPs affected by wavelength and polarization of light in fiber, (3) change in excitation ondition of SPPs caused by shape of the MIM structure and twin hole, and (4) effectiveness of additional nanostructures that are aimed at focusing control of localized SPPs located around the corner of nano-hole was studied.
