Ultra-broadband Millimeter (mm) and Terahertz (THz) wireless communication systems are expected to help satisfy the ever-growing need for smaller devices that can offer higher speed wireless communication anywhere and anytime. The large bandwidth paired with higher speed wireless links opens up the door to a large number of novel applications such as 1) ultra-high-speed cellular links, 2) wireless short range communications for ultra-high-speed data transfer, 3) secure wireless communication for military and defense applications, 4) on-body sensors for health monitoring systems. To enable future mm- and THz-range wireless communications for these different applications, it is imperative to understand propagation mechanisms and develop good channel models.
This talk compares propagation characteristics of three frequency bands: 30 GHz (26-40 GHz), 140 GHz (110-170 GHz) and 300 GHz (300-316 GHz), discusses propagation mechanisms that are prevalent at these frequencies and proposes techniques for modeling THz wireless channels.
Alenka Zajic is an Associate Professor in the School of Electrical and Computer Engineering at the Georgia Institute of Technology. She has received the B.Sc. and M.Sc. degrees from the University of Belgrade, Belgrade, Serbia, in 2001 and 2003, respectively, and the Ph.D. degree in electrical and computer engineering from the Georgia Institute of Technology, Atlanta, in 2008. Before joining Georgia Tech, Dr. Zajic was a post-doctoral fellow in the Naval Research Laboratory and visiting faculty in the School of Computer Science at the Georgia Institute of Technology. Dr. Zajic's research interests span areas of electromagnetics, wireless communications, and computer engineering. Her research is focused on studying propagation and enabling communication in challenging environments such as vehicle-to-vehicle wireless radio communications, underwater acoustic communications, and inside a processor chip.
Dr. Zajic was the recipient of the 2017 NSF CAREER Award, 2012 Neal Shepherd Memorial Best Propagation Paper Award, the Best Student Paper Award at the IEEE International Conference on Communications and Electronics 2014, the Best Paper Award at the International Conference on Telecommunications 2008, the Best Student Paper Award at the 2007 Wireless Communications and Networking Conference, and the Dan Noble Fellowship in 2004, which was awarded by Motorola Inc. and the IEEE Vehicular Technology Society for quality impact in the area of vehicular technology. She was an editor for IEEE Transactions on Wireless Communications 2012-2017.
