摘要：

This investigation presents an observation of enhanced optical transmission through an Al film that is perforated with microcells that are arranged in random structures. The dispersion relations of the Al/p-Si surface plasmon polariton in these structures with individual microcells with 3x3, 6x6, 9x9, 12x12, and 16x16 hole arrays of hexagonal were deduced. The transmission peak wavelength is determined from the spatial period of the microcell arrays. The random structure provides multicolor light transmission, which can be exploited in infrared wavelength-selective devices. (c) 2007 American Institute of Physics.
