We present theoretical calculations of the optical transmission through subwavelength apertures in a conducting screen of finite thickness. The results are employed to study the origin of the enhanced transmission observed in experiments where randomly distributed small holes of various subwavelength sizes are fabricated in a thin gold film. In the wavelength spectrum from 350 nm to 650 nm, a number of strongly enhanced transmission peaks are observed. These transmission peaks can only be observed in the near field. We discuss the experimental results in the light of the model calculations.
