  • 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...

  • An Interactive Tool for Teaching Transmission Line Concepts

    Creator:
    Scheible, Keaton
    Abstract:
    In college transmission lines courses, students are expected to understand how different circuit configurations affect the signals on a transmission line. Having a way to visualize these signals can greatly improve their learning experience. This thesis details the development of an open source, interactive learning tool used to illustrate fundamental...

  • Electrical recommendations and formulas for metal fill in radio-frequency integrated circuits

    Creator:
    Gaskill, Steven
    Abstract:
    With increasing transistor operating frequencies, interconnects and passive devices are becoming performance limiters in integrated circuit (IC) designs. To combat this, the interconnect layers above the active silicon are trending toward low-κ dielectrics and Cu metallization. The use of these new materials has popularized chemical mechanical polishing (CMP) to planarize...

  • Analysis and modeling of multi-mode effects in coplanar waveguide bends

    Creator:
    Senguttuvan, Rajarajan
    Abstract:
    A novel method for modeling bends in coplanar waveguides (CPWs) is described. The CPW can be viewed as a pair of parallel coupled quasi-slot lines. Bends in the CPW are modeled as a non-uniform coupled line system in terms of their even- and odd- mode characteristics. This modeling approach is...

  • Model development via delay extraction for the time-domain simulation of lossy transmission lines.

    Creator:
    Blevins, Chris
    Abstract:
    This thesis presents two new approaches for the broadband, time-domain modeling of lossy transmission lines. Each approach is based on an alternative derivation of delay extraction in order to separate the line's linear phase from its attenuation and dispersion. Augmentation networks represent the derived attenuation networks as rational function approximations....
