Electromagnetic simulation of light wave interaction at around a tip of single mode optical fiber, which is formed of circular truncated cone shape, has been studied numerically by COMSOL Multiphysics and the RF Module (and Wave Optics Module). The fiber tip has specific nanostructure of asymmetric metal/insulator/metal (MIM) layers coupled with subwavelength holes. Behavior of surface plasmon polaritons excited at around the complex nanostructure will be presented with several basic experiments.
