IEEE Computer Graphics and Applications 11 The Optical Diagnostics and Applications Laboratory (ODALab) is investigating methods and technology for 3D visualization and imaging. Specifically, we’re integrating and assessing systems driven by real-world applications that can benefit from or enhance distributed collaborative environments. Although optics is at the core of the research program, th...

Recent developments in the field of metamaterials have revealed unparalleled opportunities for "engineering" space for light propagation; opening a new paradigm in spin- and quantum-related phenomena in optical physics. Here we show that unique optical properties of metamaterials (MMs) open unlimited prospects to "engineer" light itself. We propose and demonstrate for the first time a novel way...

During the last five years, Oerlikon Aerospace developed and implemented engineering processes. In this paper, we discuss the application of risk management to the re-engineering of operator console stations of a missile weapon system. We briefly describe the systems engineering process. Finally, twelve lessons learned are discussed. PROCESS DEVELOPMENT BACKGROUND Oerlikon Aerospace (OA) is the...

The optical properties of plasmonic dipole and bowtie nanoantennas are investigated in detail using the Green's tensor technique. The influence of the geometrical parameters (antenna length, gap dimension and bow angle) on the antenna field enhancement and spectral response is discussed. Dipole and bowtie antennas confine the field in a volume well below the diffraction limit, defined by the ga...

In the last few years various techniques have been suggested to improve the performance of high capacity optical communication systems. In particular, the generation of optical solitons, the resolution of the limitations imposed by the chromatic dispersion and the performance of WDM systems and networks have been thoroughly discussed and investigated. In this paper it will be summarised some of...

Optical 3D sensors are used as tools for reverse engineering: First the shape of an object is digitized by acquisition of multiple range images from different view points. Then the range images are registered and the data is turned into a CAD description, e.g. tensor product surfaces, by surface modeling software. For many applications however it is sufficient to generate a polyhedral surface. ...

Computational micromagnetics plays an important role in design and control of magnetostrictive actuators. A systematic approach to calculate magnetic dynamics and magnetostriction is presented. A finite difference method is developed to solve the coupled Landau-Lifshitz-Gilbert(LLG) equation for dynamics of magnetization and a one dimensional elastic motion equation. The effective field in the ...

Optical metasurfaces-patterned arrays of plasmonic nanoantennas that enable the precise manipulation of light-matter interactions-are emerging as critical components in many nanophotonic materials, including planar metamaterials, chemical and biological sensors, and photovoltaics. The development of these materials has been slowed by the difficulty of efficiently fabricating patterns with the r...

nanofber  mats  of  poly(ε-caprolactone)/nanoclay  nanocomposites  were fabricated by electrospinning. the effects of the solution concentration and  the  nanoclay  content  of  nanocomposite  materials  on  the  fnal nanofber  structure were  investigated. morphology  and  diameter  of  the  nanofbers were studied using optical and scanning electron microscope. it was observed that the  poly(ε...
