Fall 2012
Recent proliferation of low-cost and lightweight GPS tracking devices led to a large increase in the amounts of collected mobility data. The rapidly emerging field of location-based services requires accurate and informative knowledge mining from these large quantities of data. One such mobility...

Theory and Applications of a Uniplanar Transmission-Line Metamaterial-Inspired Electromagnetic Bandgap Structure
DownloadFall 2015
A multitude of planar electromagnetic bandgap structures (EBGs) have been proposed for the suppression of parallel-plate waveguide (PPW) and surface-wave (SW) modes at microwave frequencies. Some of these structures have been well-modelled with transmission-line theory, however, these structures...
