  • The Design of an On-Chip Silicon Photonic Diode 

    Okikiola, Olaniyan (2013-05-13)
    This work presents numerical calculation of electromagnetic waves in unidirectional on-chip silicon optical diodes. An original optical diode, designed by Wang et. al. [Opt. Express. 19, 26948-26955 (2011)], is based on ...

  • Electro-Magnetic Duality, Magnetic monopoles and Topological Insulators 

    Nounahon, Mahougnon Philippe (2013-05-13)
    The Maxwell equations of electrodynamics acquire an additional symmetry if one assumes the existence of hypothetical particles-magnetic monopoles, carrying a magnetic charge. The additional internal symmetry is the ...

  • Femtosecond Laser Surface Texturing of Materials for Various Applications 

    Nforneh, Benjamen (2013-05-13)
    Femtosecond lasers represent an electromagnetic field with field intensities approaching and even exceeding atomic binding field. When irradiated on a target, the material responses change from linear to nonlinear within ...

  • Fundamentals of Laser Dynamics 

    Sanni, Dahiru Muhammad (2013-05-13)
    The thesis presents the modeling and simulation of three types of lasers namely; Semicondoctor laser, Solid state laser and CO 2 laser. The rate equations were derived and simulated to examine the dynamic behaviour of the ...

  • Influence of Molecular Polarizability on the Active Layer of Organic Photovoltaic Cells: A case study of Poly(3-hexylthiophene) 

    Cornah, Bennie Elizabeth (2013-05-13)
    The complexity of the microstructure of the active layer in organic photo- voltaics (OPVs) poses a unique challenge in improving the efficiency of OPV devices. Molecular dynamics (MD) simulation provides a direct route ...

  • Nonlinear Effect in-flow in Porous Duct 

    Hafeez, Yusuf Hafeez (2013-05-13)
    In general, it is assumed in some non viscous flows that the flow velocity is constant at a cross-section. In this thesis, If we impose more realistic boundary conditions by, for example, introducing viscosity,and suction ...

  • Simulation of Carbon Nanotube Growth 

    Ogunbunmi, Michael Olawale (2013-05-13)
    The basic understanding of the underlying techniques of growing Carbon Nanotubes (CNTs) with a specific chirality is still obscure and needs to be understood so as to properly harness its potentials. Using both Classical ...
