Physics Dissertation Defense (Fri. 19 Sep, 2014 9:00 am - 10:00 am)
Doctoral candidate Michael Stock will defend his dissertation, titled, "Broadband Interferometry of Lightning." He will discuss how he has developed a broad bandwidth interferometer capable of recording the VHF radio emission over the entire duration of a lightning flash. The standard processing techniques have been redeveloped from scratch using a digital cross correlation algorithm. This algorithm can and does locate sources as faint as the noise level of the antennas, typically producing 100,000 or more point source locations over the course of a lightning flash. 9 a.m. in the Tripp Room of the Skeen Library (room 212).
