A coupled magnetic resonator waveguide, composed of a contacting gold nanosphere chain on a gold slab, is proposed and investigated. A broadband coherent magnetic plasmon mode can be excited in this one dimensional nanostructure. By employing the Lagrangian formalism and the Fourier transform method, the dispersion properties of the wave vector and group velocity of the magnetic plasmon mode are investigated. Small group velocity can be obtained from this system which can be applied as subwavelength slow wave waveguides.
提出并研究了一种由金平板上接触的金纳米球链组成的耦合磁谐振器波导。在这种一维纳米结构中可以激发宽带相干磁等离子体模式。通过采用拉格朗日形式和傅里叶变换方法，研究了磁等离子体模式的波矢和群速度的色散特性。该系统可以获得小群速度，可作为亚波长慢波波导应用。
