基于非共振原理的光异常透射现象(EOT)可以实现宽频带透射,对宽频带光收集与激发具有重要意义.为实现宽频透射,本文设计了亚波长金属圆孔阵列,并应用有限元方法研究了该结构的透射特性.结果表明,金属圆孔阵列可实现宽频透射.此外,本文还研究了入射光偏振方向、圆孔半径以及横向周期对金属圆孔阵列透射特性的影响.这些结果对设计非共振宽频透射的金属孔洞结构具有一定的指导意义.
In 1998,T.W.Ebbesen first studied the optical transmission properties of a periodic subwavelength rectangular hole in a thin metal film and found that light
