  • Fabrication and geometrical characterization of metal and metal-dielectric composite periodic nanostructures

    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...

  • 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...

  • On-chip crosstalk suppression schemes using magnetic films for RF/microwave applications

    Creator:
    Sligar, Arien
    Abstract:
    The primary objective of the thesis research is to study novel schemes of on-chip crosstalk suppression employing magnetic films at microwave frequencies. Since extraction of various material properties of the magnetic films is essential for successful application of the proposed method, the research also involves development of a new material...

  • Broadband modeling of on-chip transformers for silicon RFICs

    Creator:
    Rapolu, Kavitha
    Abstract:
    Magnetically coupled passive transformers are increasingly integrated on-chip for various analog and radio frequency (RF) applications including direct current (DC) isolation, impedance transformation/matching, and conversion between single-ended and differential signals. A primary motivation for the on-chip integration of transformers is the overall size reduction and reduced cost. However, the performance...

  • Computational and experimental investigation of steady flow fields, turbulence, and hemodynamic wall stresses in patient-specific abdominal aortic aneurysm models

    Creator:
    Edgar, Erik S.
    Abstract:
    Steady flow fields and flow-induced wall stresses have been evaluated by experimental measurements and computational fluid dynamics (CFD) analysis in a series of patient-specific abdominal aortic aneurysm (AAA) models, over a range of Reynolds numbers (Re) from 125 to 3000 (500 to 3000 for CFD). Experimental methods used particle image...

  • Mode patterns in quadrupole resonator with anisotropic core

    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...
