  • 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...

  • A study of actinide de-excitation through neutron emission from the deuteron induced fission of ²³⁸U

    Creator:
    Sprunger, Peter Hayden
    Abstract:
    The process of de-excitation of the actinides is a very important question in both pure and applied science. In this dissertation the process was studied using the neutrons emitted in coincidence with fission induced by the bombardment of ²³⁸U with 14.85 MeV deuterons. Neutrons can be emitted at multiple stages...
