(author)The knowledge of the near-field of extra-ordinary transmission through hole-arrays is mostly theoretical; there is less experimental validation of the theory. We study the near-field properties by measuring fluorescent molecules that are immersed in a solution and their Brownian motion. The measurements are performed by filling the space above...conference paper 2006

Docter, M.W. (author), Young, I.T. (author), Kutchoukov, V.G. (author), Bossche, A. (author), Alkemade, P.F.A. (author), Garini, Y. (author)When light passes through a hole smaller than the wavelength of the light, the transmission is very low and the light is diffracted. This however changes if holes are arranged in a periodic array on metal. In that case the light couples to surface plasmons; this results in enhanced transmission, spectral selection and a small angular diffraction...conference paper 2005
