The ever increasing need for regional and global roaming together with continuous advances in wireless communication standards continue to push future transceivers towards an ability to support multi-mode operation with minimal increases in cost, hardware complexity, and power consumption. RF channel-select filter banks pose a particularly attractive method for achieving multiband reconfigurability, since they not only provide the needed front-end reconfigurability, but also allow for power efficient and versatile transceiver designs, e.g., software-defined radio. Such channel-select...

As interest in renewable energy grows on both research and policy fronts, energy storage likely represents one of the most viable solutions to the problems posed by the intermittency and irregularity of renewable resources. While new classes of materials promise improved performance of energy storage systems, understanding energy storage electrode architecture and fabrication at the micro-scale allows us to fully leverage performance along different dimensions.

Complex engineering systems ranging from automobile engines to geothermal wells require specialized sensors to monitor conditions such as pressure, acceleration and temperature in order to improve efficiency and monitor component lifetime in what may be high temperature, corrosive, harsh environments. Microelectromechanical systems (MEMS) have demonstrated their ability to precisely and accurately take measurements under such conditions. The systems being monitored are typically made from metals, such as steel, while...

2012
The structure and chemistry of nanoparticles and polymers are interesting for applications in electronics and sensors. However, because they are outside of the standard material set typically used for these applications, widespread use of these materials has not yet been realized. This is due in part to the limited ability of traditional manufacturing processes to adapt to these unique materials. As a result, several alternative manufacturing methods have been developed, including nanoimprint lithography,...

Optical interconnects are the next evolutionary step for computer server systems, replacing traditional copper interconnects to increase communication bandwidth and reduce overall power consumption. A variety of implementation techniques to bring optics to the rack-to-rack, board-to-board, and chip-to-chip scale are heavily pursued in the research space. In this dissertation we present a micro-electro mechanical systems (MEMS) based free-space optical link for board-to-board interconnects.

As with any free-space optical system, alignment is critical for the correction of undesired...
