A New Class of Resonant Metasurfaces Based on Highly Subwavelength Metamaterial-Lined Apertures and Metamaterial-Coated Discs
DownloadSpring 2019
This work presents analytical, numerical and experimental studies of a new class of resonant metasurfaces (MTSs), which may also be classified as miniaturized-element frequency selective surfaces (FSSs). The proposed MTS unit cells consist of circular aperture or disc resonators that are made...

An examination of parent-child dyadic interaction and the impact of a parent-training program designed to support the language development of toddlers diagnosed with autism spectrum disorder (ASD)
DownloadFall 2010
Parents can effectively facilitate positive child behaviour change (Kaiser & Hancock, 2003). Their inclusion as interventionists is an essential component of autism intervention (NRC, 2001) and represents a natural step toward consistent early intervention. However, what constitutes effective...

Analysis and Design of A New Class of Miniaturized Circular Waveguides Containing Anisotropic Metamaterial Liners
DownloadFall 2016
This work presents the analysis and design of a new class of miniaturized circular waveguides containing anisotropic metamaterial liners, and reveals in detail intriguing and potentially useful propagation and radiation phenomena. An analytical construction of the liner as a homogeneous,...

Anisotropic Geodesic Filter for Speckle Noise Reduction and Edge Preservation in 2D and 3D Echocardiography
DownloadFall 2018
It is a challenge today for medical practitioners and manufacturers to improve ultrasound image quality as the technology has reached its physical limits. Ultrasound images are a great help for non-invasive diagnostics but suffer from a wide variety of artifacts such as shadowing, limited field...

Bacterial stimulation of lipid vesicle production in green microalga Dunaliella tertiolecta
DownloadFall 2019
Algae and bacteria form complex interactions through the exchange of bioactive molecules and nutrients. A wide range of phenotypes, and often their very survival, are influenced by these chemically mediated relationships, shaping the ecology and diversity of marine communities. Here we sought to...

Continuum Modelling and Analysis of a Class of One and Two Dimensional Elastic Metamaterials with Local Rotation
DownloadFall 2022
The group of materials classified as "metamaterials" have accrued great interest in the scientific community as of late for their potential to revolutionize several multidisciplinary applications. Metamaterials are defined as synthetic/man-made materials which have been engineered to possess a...

Since the development of the fluctuation dissipation theorem for electromagnetics in 1956 by Landau, Lipschitz and Rytov, field correlations have gradually come to be understood as a consistent framework for treating all optical aspects of linear response. In turn, the theory of electromagnetic...

Development and Analysis of Magnetic Carbon Nanotube and Microbubble-Assisted High Centrifugation Field Techniques For The Increase of Cell Membrane Permeability
DownloadSpring 2014
To cure diseases at the gene level, therapeutic biomaterials need to enter the cells. However, since the cell membrane is a highly selective structure, its permeability is usually very low. In this thesis, we propose two innovative and efficient methods to increase cell membrane permeability....

Electrocoalescence of Water Droplets in Oil Emulsions: Effect of Electric Fields, Surfactants, and Chemical Demulsifiers
DownloadSpring 2019
Stabilization of water-in-oil droplets during bitumen extraction and refining process poses a major challenge in the oil sands industry. These crude oil emulsions are stabilized by rigid films at water droplet-oil interfaces. The salty water remaining in oil causes equipment corrosion, catalyst...
