Speaker: Aly E. Fathy, James W. McConnell Professor, University of Tennessee, Knoxville, TN

Power combiners are widely used in many microwave circuit applications. In particular, the recent evolution of communication systems has pushed the development of higher power, and more efficient devices that are suitable to operate with solid-state devices and up to millimeter wave frequencies. This talk covers the late progress in developing both resonant and non-resonant power combiners. Recent investigations have been concerned with splitters/combiners using various techniques like radial and conical combiners, and quasi-optical techniques. Other concerns include reduced circuitry size, ease and cost of fabrication like in SIW implementation.

About the speaker:  
Aly E. Fathy (S’82–M’84–SM’92–F’04) received the B.S .E.E. degree, the B.S. degree in pure and applied mathematics, and the M.S.E.E. degree from Ain Shams University, Cairo, Egypt, in 1975, 1979, and 1980, respectively, and the Ph.D. degree from the Polytechnic Institute of New York, Brooklyn, in 1984.
In August 2003, he joined the University of Tennessee, Knoxville. Now, he is a James W. McConnell Professor and his current research interests include wireless reconfigurable antennas, see through walls, ultra-wideband systems, and high efficiency high linearity combining of digital signals for base station amplifiers. He has developed various microwave components/subsystems such as holographic reconfigurable antennas, radial combiners, direct broadcast antennas (DBS), speed sensors, and low-temperature co-fired ceramic packages for mixed-signal applications. He holds 12 U.S. patents, and has published numerous transaction and conference papers. Dr. Fathy is an IEEE Fellow, member of Sigma Xi, and Eta Kappa Nu. He was the recipient of five Sarnoff Outstanding Achievement Awards (1988, 1994, 1995, 1997, and 1999), and Chancellor’s graduate mentoring and advising excellence award 2014, Chancellor’s Research and Creativity Achievement award 2013, Lamar Alexander Prize, Chancellor Award 2011, The College of Engineering Research Fellow Award, the University of Tennessee, 2011, The College of Engineering Research Fellow Award, the University of Tennessee 2008, ECE Department, The Gonzalez Family Award for Excellence in Research, 2007 (The University of Tennessee). He is an active member of the IEEE MTT-S International Microwave Symposium (IMS) Technical Program Committee, the IEEE Antenna and Propagation Symposium, and the IEEE Radio and Wireless Steering Committee. He was the General Chair of the 2008 IEEE Radio and Wireless Conference.
