Creator:: Jackson, Dennis L.
Abstract:: We developed a model to investigate the dielectric properties of the BaTiO₃ − Bi(Zn₁/₂Ti₁/₂)O₃ (BT-BZT) solid solution, which is a relaxor ferroelectric and exhibits long range disorder. The model uses ab initio methods to determine all polarization states for every atomic configuration of 2 x 2 x 2 supercells of...

Creator:: Bhowmik, Siddhartha
Abstract:: Periodic metal and metal-dielectric composite nanostructures have been of interest from the field of plasmonics and metamaterial fabrication. In order to exploit the behavior of these unique materials in the visible region of the optical spectrum, these structures need to be significantly shorter than the wavelength of response, and hence...

Creator:: Thongrattanasiri, Sukosin
Abstract:: This thesis deals with applications of uniaxial anisotropic crystals for microcavity resonators with partially chaotic underlying ray dynamics. We develop an implementation of the scattering matrix formalism, and relate the eigenvalues and eigenvectors of the scattering matrix to the field distribution of inside the system. Using the developed technique, we...
