摘要：
The relation between the enhanced optical transmission and the unit structural features is studied by changing the unit structural features. 3D finite-difference time-domain method is employed to study the enhanced optical transmission of periodic subwavelength circular-sharps shaped hole arrays in metallic films which are deposited on a quartz substrate. The influences of the unit structural features on the enhanced optical transmission are investigated. It is found that the enhanced optical transmission strongly depends on the unit structural edge sharp features: the sharp acuity, numbers, a...
