摘 要：
Surface plasmon is considered to be the strongest interplay of both optical and electronic data transfer along a tiny metal. It has found important applications in modern nanotechnology such as magneto-optic data storage, microscopy, solar cells, sensors for detecting biological molecules, and plasmonic crystals. However, it has been difficult to solve eigenmodes of plasmonic crystals in two or three dimensions either analytically or numerically due to the metal is dispersive in frequency. We present an augmented coupline interface method for solving wave-guide modes of plasmonic crystals. They are formulated as an eigenvalue problem of the wave number along the axis of the crystal. In this formulation, the permittivity and permeability of the metallic component can be arbitrary functions of frequency. Numerical results are illustrated for different shapes of plasmonic crystals, and physical significance is discussed. In this talk, I will first give an introduction of wave-guide modes of surface plasmon. Then I will explain how to discretize the governing equations and show the corresponding numerical results.
