Periodic Pulsed Controllability with Applications to NMR
In this thesis we study a class of problems that require simultaneously controlling a large number of dynamical systems, with varying system dynamics, using the same control signal. We call such problems ensemble control ...
Nanobeam Cavities for Reconfigurable Photonics
We investigate the design, fabrication, and experimental characterization of high quality factor photonic crystal nanobeam cavities, with theoretical quality factors of \(1.4 × 10^7\) in silicon, operating at ~1550 nm. By ...
Energetic Beam Processing of Silicon to Engineer Optoelectronically Active Defects
This thesis explores ways to use ion implantation and nanosecond pulsed laser melting, both energetic beam techniques, to engineer defects in silicon. These defects are chosen to facilitate the use of silicon in optoelectronic ...
Near Shannon Limit and Reduced Peak to Average Power Ratio Channel Coded OFDM
Solutions to the problem of large peak to average power ratio (PAPR) in orthogonal frequency division multiplexing (OFDM) systems are proposed. Although the design of PAPR reduction codewords has been extensively studied ...
Accelerated Cardiovascular Magnetic Resonance Imaging Using Radial Acquisition with Compressed Sensing
Magnetic resonance imaging (MRI) is a medical imaging technique that can visualize internal organs for examination and diagnosis. It is non-invasive and ionizing radiation-free, and provides good contrast between different ...
