Verbeek, P.W. (author), Van den Berg, P.M. (author)We investigate the possibility of light beams that are both narrow and long range with respect to the wavelength. On the basis of spectral electromagnetic field representations, we have studied the decay of the evanescent waves, and we have obtained some bounds for the width and range of a light beam in the near-field region. The range...journal article 2011

Toppan, F. (author), Verbeek, P.W. (author)In this paper, we address the problem of constructing a class of representations of Clifford algebras that can be named “alphabetic (re)presentations.” The Clifford algebra generators are expressed as m-letter words written with a three-character or a four-character alphabet. We formulate the problem of the alphabetic presentations, deriving the...journal article 2009

Verbeek, P.W. (author), Dijk, J. (author)The invention relates to a method of transforming a colour image, wherein for each separate pixel a measured level of lightness, a measured chroma and a measured colour is determined, followed by a predetermined adjustment in the three-dimensional level of lightness, chroma and colour, wherein a. for each separate pixel a direction of adjustment...patent 2004

Garini, Y. (author), Kutchoukov, V.G. (author), Bossche, A. (author), Alkemade, P.F.A. (author), Docter, M.W. (author), Verbeek, P.W. (author), Van Vliet, L.J. (author), Young, I.T. (author)Recently, an extraordinary transmission of light through small holes (<200 nm) in a thin metallic film has been described. This phenomenon has been shown to be the result of the photon-plasmon interaction in thin films where a periodic structure (such as a set of holes) is embedded in the film. One of the extraordinary results is that the beam...conference paper 2004

Verbeek, P.W. (author), Logtenberg, H. (author), Vos, H.C.L. (author)An imaging device (14) on the conveyor line (2) is used to determine slaughter-relevant anatomical parameters of the animal (4). A control device (17) connected to the imaging device is used to control the processing stations (5-12) on the slaughter line, depending on the measured parameters. A slaughter line for domesticated animals such as...patent 2003

Verbeek, P.W. (author), Meens, B.C.H. (author), Young, I.T. (author)The invention relates to an apparatus for determining a three-dimensional shape of an object from a two-dimensional image, comprising a light source for illuminating the object, and a detector for forming an image of the illuminated object, wherein the light source emits a pattern of substantially needle-like light beams that are directed at the...patent 2002
