Design and simulation of a short, 10 MV, variable energy linear accelerator for use in linac-MR systems
DownloadFall 2016
Hybrid linac-MR devices are currently being designed and constructed by several groups around the world which combine a linear accelerator with an MRI in order to enable real-time 3D imaging to visualize tumor movement during external beam radiotherapy treatments. Each of the current systems is...

Development of an optical biosensor based on Mach-Zehnder Interferometry for detection of Listeria monocytogenes
DownloadFall 2013
Label-free optical biosensors are widely used for the detection of pathogens due to their low-cost, real-time detection and high sensitivity. A Mach-Zehnder Interferometer (MZI) based biosensor has been developed for the detection of gram-positive bacteria, Listeria monocytogenes. An extensive...

This thesis explores the dynamics and sensing performance of silicon quantum dot (SiQD) ensembles coupled to the whispering gallery modes (WGMs) of spherical and cylindrical microcavities. The first project investigated the possibility of observing Purcell effects in an ensemble of QDs coupled to...

This thesis focuses on the photoluminescence (PL) of free-standing silicon quan- tum dots (QDs). Large changes in the emission spectrum were found to occur when the QDs were exposed to different environments while undergoing short-wavelength laser irradiation, a phenomenon that was the main focus...

Miniaturization of Microwave to Millimeter-Wave Integrated Waveguides and their Applications
DownloadFall 2019
The integration of waveguide technology at the planar level has been a crucial development for the successful realization of 5G, the future fifth generation cellular network. The demand for mobile networks with faster speeds, lower latencies, and denser connectivity scenarios continues to drive...

Silicon nanocrystals (Si-NCs) have been suggested for sensing and lasing applications due to their low-toxicity and compatibility with existing microelectronic technologies. Their broad luminescence, due to homogeneous (150 meV or 40 nm at room temperature) and inhomogeneous broadening, may...
