报 告 一: 浅谈学术类职业的准备与规划北邮、清华、佐治亚On Pursuing an Academic Career

内容摘要: In this talk, the speaker will first go through his experience of both research and life as a Ph.D. student and a professor, which aims to show a typical road path of preparing and pursuing an academic career. Then, he will share his understanding on what is research and what are the criteria of high quality research. Finally, the speaker will introduce the current research projects in his group, including the metamaterial enhanced wireless communications and networking, underwater cyber physical systems, mmWave communication and security, and wireless intra-body sensor networks.   

报 告 二: Reconfigurable Wireless: From Active Metamaterial Spherical Antenna to mmWave Reflector Array

内容摘要: In this talk, two types of reconfigurable smart wireless systems are discussed. In the first half of the talk, the magnetic induction wireless communication system using active metamaterial spherical antenna is introduced. Such technique is used to achieve long range underground and underwater communication with portable size devices. In particular, the Metamaterial-enhanced Magnetic Induction (M2I) communication mechanism is first presented. Then the active elements are added to overcome the metamaterial loss and enable the configurability. Finally, based on the performance analysis, the full-duplex M2I multi-hop transmission strategy is discussed as an application of the active M2I system. In the second half of the talk, the mmWave WLAN system (802.11ad) using reconfigurable reflector array is introduced. Such technique is designed to establish robust mmWave connections for indoor networks even when all the possible links are blocked by obstructions. First, the reconfigurable 60 GHz reflect-array is designed, implemented, and modeled. Then the three-party beam-searching protocol is designed for the reflect-array-assisted 802.11ad networks. Finally, the optimal array deployment strategy is developed to minimize the link outage probability in indoor mobile mmWave networks.
