Abstract: Tremendous advancements in the design of small, radio-frequency (RF) tags have enabled tracking systems for enhanced sports analysis and player training; however, conventional tracking systems based on propagating electromagnetic waves (e.g., the global positioning system or ultra-wideband systems) suffer reduced accuracy when the line-of-sight is blocked. In this talk, I will describe a system that uses quasistatic magnetic fields to locate an American football when players block the line-of-sight. I will discuss the motivation, technical details, and applications of the system along with an overview of my research background and future research interests.
Bio: Joshua Griffin received the B.S. degree in engineering from LeTourneau University in 2003, and the MSECE and Ph.D. degrees from the Georgia Institute of Technology (Georgia Tech) in 2005 and 2009, respectively. In 2004, he joined the Propagation Group at Georgia Tech where he researched UHF and microwave propagation for backscatter radio. He received the Graduate Research Assistant Excellence Award from the Electrical and Computer Engineering Department at Georgia Tech in 2009. He has been with the Radio and Antennas Group at Disney Research, Pittsburgh since 2009 where he pursues his research interests in applied electromagnetics including projects on radio wave propagation, radiolocation, and backscatter radio.
