摘要：

Metal films perforated with two types of Sierpinski carpet patterns (SCP) are fabricated on silicon wafer, where one pattern possesses open square aperture as the building block and the other has square ring-shaped aperture as the building block. Enhanced transmissions are observed in both structures. However, for SCP made of square ring-shaped apertures, resonance of surface plasmon of both surface and localized modes has been identified. This feature does not exist in SCP made of open square apertures. This finding provides an effective way to control the extraordinary transmission through the metal film perforated with fractal-like structures. (C) 2008 American Institute of Physics.
