Numerical simulations of surface plasmon gap waveguides for nanometric optical circuits

摘要

Numerical simulations for understanding fundamental characteristics of the surface plasmon polariton gap waveguide (SPGW) has been demonstrated. The SPGW excited through an aperture have been demonstrated by the three-dimensional simulations using a volume integral equation method. Complex propagation constants calculated by the Method of Lines (MoL) has been shown. Applications of SPGWs to the nanosize E-plane planar optical circuits are also demonstrated.
