文摘

A sub-microsized gold-coated quadrumer was successfully obtained on a resin. The reflectance of quadrumer was sensitive to the thickness of the coated gold layer. Quadrumer showed higher order modes of surface plasmon resonance in visible range. The quadrupole mode of surface plasmon in quadrumer theoretically appears at 3.4 μm.
