  • magneto photonic crystal slab waveguides with lower refractive index silica Claddings
    IEEE Photonics Technology Letters, 2007
    Co-Authors: Naoya Kono, Masanori Koshiba
    Abstract:

    This letter proposes a new form of magneto-photonic crystal slab waveguides including nanoporous SiO2, with an extremely low refractive index, as the Cladding Material. These structures allow us to achieve physical strength and to render unnecessary holes extending to Cladding layers. Our letter investigates the significance of the waveguide geometry for nonreciprocal phase shifts and losses, using a three-dimensional finite-element method with periodic boundary conditions. The guided modes exhibit small losses well below the light line and high nonreciprocal phase shifts with appropriate parameters, according to the calculations in this letter

  • resonance self shielding methodology of new neutron transport code stream
    Journal of Nuclear Science and Technology, 2015
    Co-Authors: Sooyoung Choi, Ser Gi Hong
    Abstract:

    This paper reports on the development and verification of three new resonance self-shielding methods. The verifications were performed using the new neutron transport code, STREAM. The new methodologies encompass the extension of energy range for resonance treatment, the development of optimum rational approximation, and the application of resonance treatment to isotopes in the Cladding region. (1) The extended resonance energy range treatment has been developed to treat the resonances below 4 eV of three resonance isotopes and shows significant improvements in the accuracy of effective cross sections (XSs) in that energy range. (2) The optimum rational approximation can eliminate the geometric limitations of the conventional approach of equivalence theory and can also improve the accuracy of fuel escape probability. (3) The Cladding resonance treatment method makes it possible to treat resonances in Cladding Material which have not been treated explicitly in the conventional methods. These three new meth...
