  • Electromagnetic properties of anisotropic plasmonic metamaterials

    Creator:
    Elser, Justin Lee
    Abstract:
    In this dissertation we study the electromagnetic properties of plasmonic metamaterials. We develop an analytical description to solve the fundamental problem of free-space scattering in planar plasmonic systems by utilizing anisotropic metamaterials. We show with exact numerical simulations that these manufactured materials do completely eliminate the scattering, and even in...

  • An extension of the quantum theory of scattering to the non-asymptotic regime using Bohmian trajectories

    Creator:
    Stenson, Jared R.
    Abstract:
    Quantum mechanics provides a conventional theory of scattering that is limited in at least two ways: it focuses exclusively on the asymptotic regime and, in a more general sense characteristic of all quantum descriptions, provides no concrete account of individual particle evolution in spacetime. This is particularly true during the...

  • New computational methods for determining antikaon-nucleus bound states

    Creator:
    Fink, Paul J., 1954-
    Abstract:
    Optical potential for antikaon-nucleus strong interactions are constructed using elementary antikaon-nucleus potentials determined previously. The optical potentials are used to determine the existence of a kaon hypernucleus. Modern three dimensional visualization techniques are used to study model dependences, new methods for speeding the calculation of the optical potential are developed,...

  • Exchange interaction studies in magnetic semiconductors by neutron scattering

    Creator:
    Wiren, Zachary Quincy
    Abstract:
    Theories predict that making a dilute magnetic semiconductor strongly p -type would allow it to remain ferromagnetic at room temperature. This is of intrest as a ferromagnetic semiconductor would allow for a great many applications in the field of spintronics. Neutron scattering experiments were undertaken to better understand the antiferromagnetic...
