  • Finite element modeling of dielectric waveguides

    Creator:
    Vishakhadatta, Gannavaram D.
    Abstract:
    Dielectric waveguides are becoming important for their numerous applications in integrated optics. The study of dielectric waveguides by analytical techniques is not sufficient for many variations in waveguide shape, anisotropy, and inhomogeneity commonly encountered in waveguide materials. This work studies the finite element method as an accurate tool for the...

  • Local field effects on dielectric properties of solids

    Creator:
    Canfield, Lingzhou Li
    Abstract:
    Local field effects on the dielectric properties of solids have been studied for three-dimensional and two-dimensional crystals by using two kinds of dipole models: an atomic dipole model in which dipoles coincide with atom sites and a bond dipole model in which dipoles are placed along bond directions. Local fields...
