Janssen, O.T.A. (author), Urbach, H.P. (author), 't Hooft, G.W. (author)The excitation of surface plasmons by subwavelength slits in metal films is studied using a rigorous diffraction model. It is shown that the plasmon is launched by a slit in antiphase with the incident magnetic field. This is true independent of slit width and of the metal used. Using this phase information, maxima and minima in transmission are...journal article 2006

Janssen, G.C.A.M. (author), Tichelaar, F.D. (author), Visser, C.C.G. (author)Stress in hard films is the net sum of tensile stress generated at the grain boundaries, compressive stress due to ion peening, and thermal stress due to the difference in thermal expansion of the coating and substrate. The tensile part due to grain boundaries is thickness dependent. The other two contributions are not thickness dependent....journal article 2006

Janssen, T.T. (author)As ocean surface waves radiate into shallow coastal areas and onto beaches, their lengths shorten, wave heights increase, and the wave shape transforms from nearsinusoidal to the characteristic saw-tooth shapes at the onset of breaking; in the ensuing breaking process the wave energy is cascaded to small-scale turbulent motions in the surf zone....doctoral thesis 2006

Janssen, M.H.A. (author)The beta-lactam antibiotics are the most important class of antibiotics used today. In the last decade the production routes of these antibiotics have shifted from chemical routes to more environmentally benign routes using the enzyme penicillin G acylase. For both practical and economical reasons the enzyme is immobilised. As the kinetically...doctoral thesis 2006

(author)Phase Measurement Interferometers (PMI) are widely used during the manufacturing process of high quality lenses. Although they have an excellent reproducibility and sensitivity, the set-up is expensive and the accuracy of the measurement needs to be checked frequently. This paper discusses an alternative lens metrology method that is based on an...conference paper 2006

Janssen, M.F.W.H.A. (author), Kuk, G. (author)Within the public sector, the deployment of enterprise architecture is often an attempt to address the decentralization/centralization relationships to improve the links between the central and the local governments. The underlying aim is to provide a better structure to manage the diverse, independent and local IT-related projects and...conference paper 2006

(author)The judgment of the imaging quality of an optical system can be carried out by examining its through-focus intensity distribution. It has been shown in a previous paper that a scalar-wave analysis of the imaging process according to the extended Nijboer–Zernike theory allows the retrieval of the complex pupil function of the imaging system,...journal article 2005

Grachev, S.Y. (author), Tichelaar, F.D. (author), Janssen, G.C.A.M. (author)We studied the tensile stress and grain-width evolution in sputter-deposited Cr films with thickness from 20?nm to 2.7??m. Films were deposited in an industrial Hauzer 750 physical vapor deposition machine at 50–80?°C. The films exhibited a columnar microstructure. A power law behavior of the tensile stress as well as of the average grain width...journal article 2005

Janssen, M.F.W.H.A. (author), Cresswell, A.

As a result there is mounting pressure to move from disparate systems operating in parallel toward a shared architecture designed to support information exchange and cross...conference paper 2005

Janssen, M.F.W.H.A. (author), Cresswell, A. (author)Traditionally, government agencies are organized vertically around departments. Many local government agencies are looking for ways to develop an integrated architecture. Many architectural methods are available, however, they remain often abstract, provide limited support for the translation of the concepts to a concrete situation, and have...conference paper 2005
