Transparent transducers and fast electronics for next-generation ultrasound and photoacoustic imaging
DownloadSpring 2022
Most ultrasound transducers are opaque. Transparent transducers could lead to novel applications, including combined optical and ultrasound imaging, photoacoustic imaging and other multi-modality systems. This thesis introduces transparent capacitive micromachined ultrasound transducers and...

Spring 2014
Emerging devices, such as those based on carbon (in the form of graphene or nanotubes) or III-V compound semiconductors, are constructed on an atomic scale, where the transport is governed by the Schrödinger equation of quantum mechanics or the Boltzmann transport equation (BTE) of semi-classical...

Treatment of early age-related macular degeneration in a cell culture model with femtosecond laser pulses
DownloadFall 2017
This thesis work focuses on obtaining preliminary results demonstrating the isolated femtosecond laser ablation of sub-RPE drusen-like deposits. Age-related macular degeneration (AMD) is an age-onset degenerative condition of the retina that can lead to legal blindness. The early stages of the...

Fall 2020
This thesis describes the design, fabrication and characterization of tunable bandpass filter devices based on optical tunneling. The filters were manufactured from the hybrid assembly of first hemi-cylindrical and later hemi-spherical lenses, with a multi-layer thin-film stack deposited on the...

Ultra Wideband Radar Technology and Signal Processing Methods for the Multiphase Flow Monitoring and Tunnel Boring Operations
DownloadSpring 2024
Ultra-wideband (UWB) radar technology can provide solutions for many existing challenges in the industry. In this research, we tackle three existing problems in the oil industry and tunnel construction operations. First, microwave imaging and associated signal processing techniques are proposed...

Fall 2018
This thesis presents theoretical and experimental work on the generation and control of ultrashort electron pulses via surface plasmon (SP) waves. As such, new methods are presented to specifically control various beam parameters such as direction, kinetic energy, pulse duration, and...

Fall 2018
High-frequency ultrasound (>20MHz) offers promising opportunities for high-resolution blood flow imaging of the microcirculation at superficial depths owing to high backscatter coefficient and high resolution. Because time-of-flight is minimal at these superficial depths, focused beam scanning...
