各位老师，大家好！ 美国中佛罗里达大学Xun Gong教授来复旦访问，欢迎感兴趣的老师和同学参加！ 下面是详细信息: 题目：Customizable Antenna Array Using Reconfigurable Slot-Ring Antennas 报告人：Xun Gong 教授 （University of Central Florida） 时间：2017年12月15日（周五） 上午10:00-11:00 地点：光华楼东主楼1101 联系人：杨国敏 Abstract: Antenna arrays are widely used in many military as well as civil applications. They are typically expensive to develop and the design cycles are long. Unfortunately, due to the vastly different personalities required for various applications, the technology developed for one project cannot be easily adapted to another one, causing a lot of waste in terms of time, effort, and money. To address this need, DARPA solicits for novel system architectures and components under the Arrays at Commercial Timescale (ACT) program in order to develop a common technology which is adaptable to different personalities of communication, radar, and electronic warfare (EW) systems. In this talk, a reconfigurable slot-ring antenna array will be presented. This antenna array can switch between S- and C- band operation states. In addition, it can provide full-band instantaneous bandwidth in each band. Both V- and H- polarization states are supported. Each band has its own feeding lines. Since the S- and C-band antenna arrays have a shared aperture, this antenna array can be scaled to a large array. Biography: Xun Gong received his B.S. and M.S. degrees in Electrical Engineering from FuDan University in 1997 and 2000, respectively, and the Ph.D. degree in Electrical Engineering from the University of Michigan, Ann Arbor in 2005. He is currently a full professor in the Department of Electrical and Computer Engineering at University of Central Florida (UCF). He was with the Birck Nanotechnology Center at Purdue University, West Lafayette, IN, as a post-doctoral research associate. He served as the General Chair of the 2016 International Workshop on Antenna Technology (iWAT) and 2012 IEEE Wireless and Microwave Technology Conference (WAMICON), the Operations Chair of 2014 IEEE MTT-S International Microwave Symposium (IMS) and the TPC Chair for 2013 IEEE AP-S/URSI International Symposium on Antennas and Propagation. He served as the IEEE AP/MTT Chapter Chair in Orlando, FL during 2007-2010. He is the associate editor of IEEE Wireless and Microwave Component Letters (MWCL). He has been the recipient of the NSF Faculty Early CAREER Award for 2009-2014. He has published 106 referred Journal articles and conference papers. His current research interests include microwave filters and passive components, wireless passive sensors for harsh environment applications, antennas, phased arrays, and reflectarrays, flexible electronics, micromachining, advanced packaging, ceramic materials, polymer materials, ferroelectric materials, metamaterials, and material characterization.
