Electron Energy Loss Spectroscopy for Probing Nanophotonic Excitations at High Energy and Momentum
DownloadSpring 2019
Strong nanoscale light-matter interaction is often accompanied by ultra-confined photonic modes and large momentum polaritons existing far beyond the light cone. A direct probe of such phenomena is difficult due to the momentum mismatch of these modes with free space light however, fast electron...

In-Situ Real-Time Solids Content Measurement of Settling Oil Sands Tailings Based on a Light Scattering Technique
DownloadFall 2022
Subsurface solids content measurement of oil sands tailings ponds is essential for tailings management and land reclamation activities. Currently, solids content is primarily measured by manual sampling and offline analytical methods. Light scattering can be used to determine particle sizes and...

Multiple access interference (MAI) in time-hopping (TH) ultra-wideband (UWB) systems is known to be non-Gaussian. Several statistical models have been proposed for the MAI, and based on them various nonlinear single-user receivers have been designed. In this thesis, an accurate mathematical model...

Nanophotonic detection of nanomechanical structures for use toward mass sensing applications
DownloadSpring 2014
Nanomechanical beam resonators show much promise for use in integrated on-chip mass sensing systems. This follows from their own very small masses and also their ability to store the mechanical energy of their oscillations to produce strong measurable mechanical response signals. To achieve...
