| 摘 要： | 由两种以上的电介质材料周期性的填充到亚波长金属狭缝中组成的系统被称为是SPP光子晶体.它可以产生带隙结构从而有效调控狭缝中的表面等离激元.对于这个系统,用等效理论计算出来的带隙宽度总是比数值模拟出来的结果要大些.对于这一误差的来源,一种猜测是,光波因能够通过金属壁直接传播而有渗漏效应.本文通过时域有限差分(FDTD)模...

| Abstract: | The so called SPP crystal is composed of a metal subwavelength slit filled periodically with two or more dielectrics,in which the photonic band gap(PBG) is generated and consequently the surface Plasmon polariton(SPP) traveling in the slit may be adjusted effectively.The PBG structure can be calculated by the theory of the effective one-dimensional photonic crystal.As the effective theory always gives the PBGs narrower little than the numerical results that are thought as the practical case,one guesstimate ... |
