(author)Recently, a novel holographic diffraction grating made of polymer slices alternated to homogeneous films of nematic liquid crystal (POLICRYPS) was realized. We study the optical performance of the POLICRYPS gratings by both numerical simulations and experiments. Characterization of the grating at normal and conical reading mount are performed....journal article 2008

Xu, Q. (author)This thesis is the summary of the development of electron diffraction into a mature method for ab initio structure determination. The progress is illustrated with the structure determination of some complicated unknown inorganic materials. The main step forwards is that it is now possible to apply electron crystallography method on solving the...doctoral thesis 2008

Xu, M. (author), Urbach, H.P. (author), De Boer, D.K.G. (author)A color and polarization separating backlight can be obtained by using a surface-relief grating made of birefringent material as an outcoupling structure on top of the lightguide. A rigorous finite element diffraction model was applied to study the polarization effect of such a grating. The diffraction of plane waves by the anisotropic grating...journal article 2007

Klimczuk, T. (author), Xu, Q. (author), Morosan, E. (author), Thompson, J.D. (author), Zandbergen, H.W. (author), Cava, R.J. (author)Mg10Ir19B16, a previously unreported compound in the Mg-Ir-B chemical system, is found to be superconducting at temperatures near 5 K. The fact that the compound exhibits a range of superconducting temperatures between 4 and 5 K suggests that a range of stoichiometries is allowed, though no structural evidence for this is observed. The compound...journal article 2006

Xu, M. (author), Stefani, F. (author), Gerbeth, G. (author)The conventional magnetic induction equation that governs hydromagnetic dynamo action is transformed to an equivalent integral equation system. An advantage of this approach is that the computational domain is restricted to the region occupied by the electrically conducting fluid and to its boundary. This integral equation approach is applied to...conference paper 2006

Xu, M. (author), Urbach, H.P. (author), De Boer, D.K.G. (author), Cornelissen, H.J. (author)The application of wire grid polarizers as efficient polarizing beam splitters for visible light is studied. The large differences between the transmissivity for different polarizations are explained qualitatively by using the theory of metallic wave guides. The results of rigorous calculations obtained by using the finite element method are...journal article 2005
