  5. 3. Pay tracing tools for high frequency electromagnetics simulations

    Author : Sandy Sefi; KTH; []
    Keywords : CEM; GTD; Ray Tracing; NURBS; Software Architecture; Shadowing;

    Abstract : Over the past 20 years, the development in ComputationalElectromagnetics has produced a vast choice of methods based onthe large number of existing mathematical formulations of theMaxwell equations. None of them dominate over the others,instead they complement each other and the choice of methoddepends on the frequency range of the electromagnetic waves. READ MORE

  6. 4. Tracing Molecular Conformations by X-ray Solution Scattering

    Author : Alexandr Nasedkin; Jan Davidsson; Pau Bernado; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In the present work the refinement of X-ray data have been used to solve different scientific problems, namely drug localization in the liposome wall, reaction kinetics of the small molecule upon excitation and resolving an ensemble of protein structures at different temperatures. The common approach included collection of X-ray scattering patterns, modelling of the system of interest in atomic level and fitting computed results to experimental data. READ MORE

  7. 5. Faceted conformal antenna arrays analyzed with the uniform theory of diffraction

    Author : Carina Marcus; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Faceted Conformal Antenna; High-frequency methods; Ray tracing;

    Abstract : Faceted conformal antenna arrays are analyzed with the uniform theory of diffraction (UTD). Parameters such as mutual coupling, scattering parameters, isolated and embedded element patterns are calculated.A ray tracing algorithm for handling rays on a faceted surface, which is needed for the UTD calculations, is also described..
