Analysis and modeling of lossy planar optical waveguides and application to silicon-based structures

Creator:: Remley, Catherine A.
Abstract:: This work is concerned with the modeling and analysis of lossy planar dielectric optical waveguides. Loss mechanisms which affect propagation characteristics are reviewed, and various representations of the propagation constant in the lossy case are defined. Waveguide structures which are susceptable to absorption and/or to leakage loss, in particular silicon-based...

Time domain modeling of electromagnetic radiation with application to ultrafast electronic and wireless communication

Creator:: Remley, Catherine A.
Abstract:: A versatile computational technique for improved time domain modeling of electromagnetic radiative systems is demonstrated. Two computational methods are combined: the finite-difference time domain (FDTD) method, a full-wave electromagnetic field solver, and the Kirchhoff surface integral formulation, a spatial transformation technique. The combined FDTD/Kirchhoff technique is shown to increase accuracy...

High-resolution electromagnetic imaging of the San Andreas fault in Central California

Creator:: Unsworth, Martyn, Egbert, Gary D., and Booker, John
Abstract:: Although there is increasing evidence that fluids may play a significant role in the earthquake rupture process, direct observation of fluids in active fault zones remains difficult. Since the presence of an electrically conducting fluid, such as saline pore water, strongly influences the overall conductivity of crustal rocks, electrical and...

Vitamin B6 status over time and its relation to symptoms of carpal tunnel syndrome

Creator:: Bolli, Andrea M.
Abstract:: Research suggests that, in individuals with carpal tunnel syndrome (CTS), low plasma pyridoxal 5'-phosphate (PLP) concentrations are related to an increased incidence and severity of symptoms associated with CTS. This study was designed to determine the relationship between plasma and red blood cell PLP concentrations and the severity and incidence...

Characterization of coupled microstrip structure using FDTD

Creator:: Kim, Yoonsuk
Abstract:: A new CAD-oriented methodology for the full-wave broadband characterization of coupled microstrip structures for RF/microwave and high-speed digital circuits is presented. The characterization methodology is based on the finite difference time domain (FDTD) technique combined with a systematic extraction procedure using the normal mode approach and multiport network concepts. The...

Analysis of planar multi-conductor multilayered structures by network analog method

Creator:: McVeety, Joseph J.
Abstract:: In this thesis the network analog method is used to analyze various planar multi-conductor structures in multilayered, lossy dielectric media. The method is based on an efficient impedance network representation of the finite difference approximation of Laplace's equation for the electric potential. Using the network analog method, the transmission line...

Generalized modal analysis of electromagnetic- and quantum-waveguide structures and discontinuities

Creator:: Weisshaar, Andreas
Abstract:: Generalized modal analysis techniques for the characterization and modeling of dissipationless planar waveguide structures and discontinuities encountered in microwave and optical integrated circuits, as well as of quantum waveguide structures and devices, are presented. The frequency-dependent transmission properties of the curved microstrip bend are derived by utilizing a second-order perturbation...
